this is not really a question... But I think you are asking why php functions inside a HTML button do not work. Well probably because php is rendered serverside and is passed to a user-browser afterwards.... it is possible to use php inside onclick... but only to display specific content (javascript function for instance)... it is not possible to let a user decide to run a specific php function by clicking a button.
Use the "static" keyword to declare a static variable within a function like shown below. <?php function fun() { static $variable; static $another_variable = ''; } ?>
A user defined function in PHP is set up of several key components.First, the function keyword; this lets PHP know that you're setting up a function. Then the function name, which lets you later use your function. After that, the parametersthe function requires to operate. Finally, just the bracketssurrounding your function, setting it apart from the rest of your code.function nameHere ($parameterOne, $parameterTwo) {functionCodeHere();}
Below is a simple example of how you could return a value in a PHP function. <?php function returnme($value) { return $value; } echo returnme('hello'); // outputs: hello ?>
It is fairly simple to check the length of a string in PHP. All you need to do is use the function strlen(). Below is an example of how it is used. <?php $my_text = "Hello"; echo strlen($my_text); // outputs 5 ?>
