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, $parameterTwo) {
functionCodeHere();
}
A simple function call <html> <body> <?php if(isset($_POST['button'])) { setValue(); // Function is called } function setValue() { echo "<br>The button property to call PHP function works"; // Your code here } ?> <input type="submit" name="button" onclick=<?php $_SERVER['PHP_SELF']; ?> /> </body> </head>
they're called user-defined functions, this is the syntax: function the_user_defined_name() { the code you want here }
function myFunction($parameter1, $parameter2) { // this function's code goes here return $returnValue; // the value returned }
The function keyword in PHP allows users to define functions beyond those built into the language, like so: function isFour ($number) { return $number == 4; }Functions in any language, including PHP, allow the developer to re-use their code. Without functions all of the code required to do the simplest of tasks must be re-written constantly; but with functions you must only write the code once and then call it whenever needed.
We can use php tags in different ways. <?php //php code to be written here ?> OR <? //php code ?> This tag will not work when we using editors such as macromedia dreamweaver. OR < script language="php"> //php code </script>

Functions are basic blocks of code that work together. Functions can be used from the core PHP or can be created by users. To create a function, use the following syntax: function function_name(arg1, arg2, ... argX) { //Any valid php code here } To use a function, use the following syntax: function_name(arg1, arg2, ... argX);
A simple function call <html> <body> <?php if(isset($_POST['button'])) { setValue(); // Function is called } function setValue() { echo "<br>The button property to call PHP function works"; // Your code here } ?> <input type="submit" name="button" onclick=<?php $_SERVER['PHP_SELF']; ?> /> </body> </head>
they're called user-defined functions, this is the syntax: function the_user_defined_name() { the code you want here }
function myFunction($parameter1, $parameter2) { // this function's code goes here return $returnValue; // the value returned }
PHP is a scripting language while Ruby on Rails is a framework based on ruby programming language. PHP is easy to learn and code while Ruby is hard to learn and code. PHP Code is a mess and difficult to find particular functions or code while ROR follows systematic development and you can easily find the required function.
