PHP Variable functions are used to assign a function's name to a variable. In this current PHP tutorial, we will study about that, how to declare php variable functions, how to assign, how to call via a variable and how to pass values.

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>


function fun()


echo "This is an example";


function disp($var){

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





$f('New Val');




This is an example
Value is:New Val
