How to Use the PHP Is_Numeric() Function

The is_numeric() function in the  PHP programming language is used to evaluate whether a value is a number or numeric string. Numeric strings contain any number of digits, optional signs such as or -, an optional decimal, and an optional exponential. Therefore, 234.5e6 is a valid numeric string. Binary notation and hexadecimal notation are not allowed.   The  is_numeric()  function can be used within an if() statement to treat numbers in one way and non-numbers in another. It returns true or false. Examples of the Is_Numeric() Function For example: ?php if (is_numeric(887)) { echo Yes; } else { echo No; } ? Because 887 is a number, this echos Yes. However: ?php if (is_numeric(cake)) { echo Yes; } else { echo No; } ? Because cake is not a number, this echos No. Similar Functions A similar function, ctype-digit(), also checks for numeric characters, but only for digits—no optional signs, decimals, or exponents allowed. Every character in the string text must be a decimal digit for the return to be true. Otherwise, the function  returns false. Other similar functions include: is_null() – Finds whether a variable is NULLis_float() – Finds whether the type of a variable is floatis_int() – Find whether the type of a variable is integeris_string() – Find whether the type of a variable is stringis_object() – Finds whether a variable is an objectis_array() – Finds whether a variable is an arrayis_bool()  Ã¢â‚¬â€œ Finds out whether a variable is a boolean About PHP PHP is an abbreviation for Hypertext Preprocessor. It is an open-source HTML-friendly scripting language that is  used by website owners to write dynamically generated pages. The code is executed on the server and generates HTML, which is then sent to the client. PHP is a popular server-side language that can be deployed on almost every operating system and platform.

Effects Of Anorexia Nervosa Essay Example For Students

Effects Of Anorexia Nervosa Essay Anorexia nervosa is a serious problem that many people are dealing with in todays society. Though this is a serious problem, the severity of the illness can easily be lessened with quick intervention from parents, friends, and other caring individuals. People who are close to the victim can notice early warning signs and symptoms, which are characteristic of this condition. Anorexia nervosa may be a life threatening illness, but can be treated if detected early on. There are many effective treatments that are currently available for patients. These different treatments will help the patient regain a healthy, normal lifestyle. The only real answer to the question of what type of people anorexia nervosa affects is that there is no valid answer even though researchers have found that the amount of people who develop anorexia nervosa is rising drastically. Researchers have also found that many patients with anorexia nervosa typically lack self-esteem and often feel that weight loss will make them more liked or even popular. There are many different symptoms that anorexics display. The symptoms can be both physical and psychological. The physical symptoms only occur after a severe amount of starvation has occurred. The symptoms often include constipation, loss of hair on the head, growth of faint body hair, low pulse rate, and the patient is unable to tolerate cold temperatures. Anorexics also experience many different endocrine problems. The psychological problems can range from social withdrawal to distortion of body image. There is no real answer as to exactly what causes anorexia nervosa. Researchers believe that environmental, psychological, and physiological factors all play a major role in the happening of this disorder. Many scientists believe that the part of the brain called the hypothalamus has a part in the development of anorexia nervosa. Other researchers think that abnormalities in particular endocrine functions may be key to discovering what may cause anorexia nervosa. There are three different ways that patients with anorexia nervosa can be treated. These treatments consist of nutritional therapy, family counseling, and psychotherapy for the patient. The foremost concern when beginning nutritional therapy is that the patient needs to gain weight. A physician can accomplish this by adding an amount of calories to a patients daily intake of food. Family counseling basically deals with the relationship between the patient and the members of the family. Psychotherapy is very necessary to the patient because it helps the individual realize the effects and the process anorexia nervosa undergoes. If a person with anorexia has symptoms of depression, antidepressants are often necessary. I agree with every aspect that the article presented. One thing that I agree with is that there are many different symptoms that a person with anorexia nervosa will often display. One of my high school friends suffered from anorexia nervosa. I first noticed that she might be dealing with this disorder when we were sophomores. She rarely came to lunch and made excuses to why she wasnt eating. Towards the end of the year she stopped coming to lunch all together and I only saw her drink bottled water. The disease got progressively worse over the next two years. By our senior year, her hair became very thin and would often fall out. It got to the point where she would get her hair cut very short in hope that nobody would question if she had a problem. Her skin began to yellow and she developed a fine type of hair that was particularly noticeably on her face and arms. She would also display signs of being very cold at all times. It got to the point where she would wear sweatshirts when it was seventy degrees outside. I had a first hand experience with anorexia nervosa, and the symptoms that were described in the article correspond with the symptoms that my friend from high school displayed. .u34cc21b94d40cca66efd1a5627291fd3 , .u34cc21b94d40cca66efd1a5627291fd3 .postImageUrl , .u34cc21b94d40cca66efd1a5627291fd3 .centered-text-area { min-height: 80px; position: relative; } .u34cc21b94d40cca66efd1a5627291fd3 , .u34cc21b94d40cca66efd1a5627291fd3:hover , .u34cc21b94d40cca66efd1a5627291fd3:visited , .u34cc21b94d40cca66efd1a5627291fd3:active { border:0!important; } .u34cc21b94d40cca66efd1a5627291fd3 .clearfix:after { content: ""; display: table; clear: both; } .u34cc21b94d40cca66efd1a5627291fd3 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u34cc21b94d40cca66efd1a5627291fd3:active , .u34cc21b94d40cca66efd1a5627291fd3:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u34cc21b94d40cca66efd1a5627291fd3 .centered-text-area { width: 100%; position: relative ; } .u34cc21b94d40cca66efd1a5627291fd3 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u34cc21b94d40cca66efd1a5627291fd3 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u34cc21b94d40cca66efd1a5627291fd3 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u34cc21b94d40cca66efd1a5627291fd3:hover .ctaButton { background-color: #34495E!important; } .u34cc21b94d40cca66efd1a5627291fd3 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u34cc21b94d40cca66efd1a5627291fd3 .u34cc21b94d40cca66efd1a5627291fd3-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u34cc21b94d40cca66efd1a5627291fd3:after { content: ""; display: block; clear: both; } READ: Titanic Differnces EssayAnother point that I agree with in the article is that a person who is dealing with this disease is a family disease that requires family therapy. The anorexic person is often a cause of severe tension within the family unit. This type of therapy helps the members of the family have a better relationship with one another. It also is a major step that will help both the patient and the family deal with this problem. It only makes sense for the family to get some sort of help along with the patient because the family will often play a major role in the onset of anorexia nervosa. I agree with this type of therapy because it will make the living situati on between the patient and the other family members more manageable. Part 3:There are many things that are found in the textbook that correspond with the article. One is that that the book stated that anorexics often have a distorted body image and often see themselves as being very fat even though they are harmfully underweight. This corresponds with the article because it also describes one of the psychological symptoms in the same manner. Another point that is discussed by both the textbook and the article that is being discussed is the initial treatment for anorexia nervosa. They both stressed that treatment should begin with weight gain. The article believes that this should be done with an increase of calories the patient has daily while the textbook considers that this should be accomplished through behavior modification. Whether weight gain is completed by an increase of calories or behavior modification, both sources agree that weight gain is very vital for the anorexic. The two sources differ on the causes of anorexia nervosa. The textbook stated that the causes of anorexia nervosa are found in the development of the individuals personality. The article stated that anorexia is a combination of three factors. The factors are environmental, psychological, and physiological. The two sources differ greatly in this specific area.

Since innovation has enabled online learning, it is important for instructors to employ effective techniques by incorporating basic active learning principles in the website’s special features. The fundamental aspect in this regard is to develop learning objectives that will help the users to identify what they are required to know by the end of the course. Technical resources and pre-existing software must also be put into consideration in the development of an interactive user interface. The instructor should therefore ensure compatibility and convenience to enable easy access by the user and that more information is available. Effectiveness and interactivity is also enhanced by securing commitment of all users such as the students, faculty, administrators and development of portals to link all of them. The use of hyperlinks, online communication and multimedia are effective when lecture contents are integrated with them creatively. The creative use of slideshows, sound, texts and images should be moderated to avoid deviation from the learning objectives. They should also be aligned with instructional design. Hyperlinks will allow the user to navigate through the pages in the educational websites. Video and audio conferencing over the internet, online discussion, emails and chartrooms provide comprehensive online communication with an effective feedback system. The user can ask questions and clarify certain topics to gauge their degree of understanding. Instructors can enhance the leaning process by creating, simple, efficient and attractive web pages. They should also provide opportunities for self-assessm ent, learning that is problem based and self-directed. On implementation, hyperlinks and online communication should be verified and monitored periodically to prevent difficulty in accessing the web-based user manuals. Benefits and Challenges There are several benefits of providing web-based manuals. Multimedia and graphics incorporated in the web-based manuals makes them attractive to the users, hence motivates them to look through and understand. The inclusion of hyperlinks allows for easy and efficient navigation of the web pages. The user is able to access more information on the particular course if techniques of online communication, hyperlinks and multimedia are applied with precision. Visual web-based manuals also have an advantage of larger space for sufficient packaging as compared to paper manual and they reduce tediousness. Challenges include difficulty in using the manuals among some learners, incompatibility with different web browsers and development of effective navigation through hyperlinks. If the user does not have online connectivity, he or she cannot access the manual. Therefore a paper manual must be produced along with the web-based manual and this increases costs.

Didelphodon - Facts and Figures

Didelphodon - Facts and Figures Name: Didelphodon (Greek for opossum tooth); pronounced die-DELL-foe-don Habitat: Swamps, lakes and rivers of North America Historical Period: Late Cretaceous (70-65 million years ago) Size and Weight: About one foot long and a few pounds Diet: Insects and small animals; possibly omnivorous Distinguishing Characteristics: Opossum-like teeth; semi-aquatic lifestyle; short, powerful jaws About Didelphodon Throughout the history of life on earth, marsupials have been mostly confined to two continents: Australia (where the vast majority of pouched mammals live today) and Cenozoic South America. However, one family of marsupialsthe pint-sized opossumshave prospered in North America for tens of millions of years, and are represented today by dozens of species. Didelphodon (Greek for opossum tooth), which lived in late Cretaceous North America alongside the last of the dinosaurs, is one of the earliest opossum ancestors yet known; as far as we can tell, this Mesozoic mammal wasnt significantly different from its modern descendants, burrowing underground during the day and hunting for insects, snails and possibly the hatchlings of prehistoric turtles at night. One of the odd things about Didelphodon is that it was apparently suited to a semi-aquatic lifestyle: the recently discovered skeleton of a nearly intact specimen, recovered near a Triceratops individual, reveals a sleek, otter-like body equipped with a Tasmanian Devil-like head and strong jaws, which may have been used to feast on mollusks in lakes and rivers, as well as insects, plants, and pretty much anything that moved. However, one shouldnt take Didelphodons guest appearances on animated TV documentaries too literally: in one episode of Walking with Dinosaurs, this tiny mammal is depicted unsuccessfully raiding a clutch of Tyrannosaurus Rex eggs, and an installment of Prehistoric Planet shows Didelphodon scavenging the carcass of a juvenile Torosaurus!

Judges of colorado state Essay Example | Topics and Well Written Essays - 500 words

Judges of colorado state - Essay Example This is a tax policy change resulting in a net returns gain in which, according to the Constitution, voters should approve (Arnold 2). In 1988, the legislature codified the judicial routine commission notion. The legislation formed a statewide commission on judicial performance. This commission oversees the appraisal of county and district court trial judges and assesses the appellate court judges. Due to the formation of this commission, it is likely that some of the judges of the Colorado state will be re-elected. This will be highly based on their performance during their service (Jean 2). The commission follow a certain procedure in assessing judges: reliability; awareness and understanding of substantive, ceremonial, and evidentiary law; communication skills; grounding, consideration, and control over judicial procedures; sentencing practices; docket administration and timely case disposition; managerial skills; regularity; efficiency in working with participants in the judicial procedure; and service to the legal occupation and the public. Based on the above criteria, most of the Colorado judges should not be re-elected. This is highly because these judges do not adhere to the above qualities (Jean 3). The court of Colorado committed further constitutional contraventions, which included assaults on property rights, gun rights, and capsized the death punishment for a convicted hijacker, rapist or murderer since a pair of jurors was suspected to have quoted biblical lines in sentencing discussions (Arnold 3). The Supreme Court has evaluated heavily, essential constitutional issues for instance taxes, schools, and the appropriate function for courts in the last few years. The court has produced contentious written verdicts on these and other concerns that affect Colorado citizens. Voters in Colorado are going to wish for

Applying strategic management in state of Qatar Essay

Applying strategic management in state of Qatar - Essay Example Cancer has been a disease that has been on the rise all over the world. The national cancer strategy is working hard to make sure that the Qatari population gets the best healthcare at home. The national cancer program holds public events so as to educate people about cancer (Manfred, 45). With more awareness, the people are able to take good care of themselves. If the ministry puts aside cash for this organization, it can help in cost that they incur while holding their events. The most important factor when it comes to any sector, whether public or private, is ensuring that all members of staff are equipped with enough skills to do their job. The Qatar foundation has opened a health care center to give services to its employees. If more of such facilities can be invested into, it would mean that the medical sector would be armed with qualified staff that is able to deal with any situation that they may face (Bodenheimer, & Brian,460) . These strategies should not lie only in the health sector, the government should work on making sure that all public sectors are better
