PHP Variable Functions:

Learn PHP Variable Function means that if a variable name has a format like this $var(), PHP will consider this as a variable function and will look for a function with a name which is assigned to it, and will try to execute it.

This variable function does not work with echo(), print(), unset() etc language constructs.

PHP Example:/strong>

<?php

function fun()

{

echo "This is an example";

}

function disp($var){

echo "<br/>Value is:".$var;

}

$f='fun';

$f();

$f='disp';

$f('New Val');

?>

 

Output:

This is an example
Value is:New Val
