Replacing function with other functions.

[Jazzy_Girl]

Hello, what php code replaces one function with another.

An example only

<?php
function a(){here is function a}

function b(){here is function b}
Code here stating that on next page load function b() will replace function a().
?>

I need something replacing the first, not just adding to it. Please let me know, thanks very much.

You can't overload functions in php.

You could define the to do different operations using an if statement.

function xyz( $a , $b , $c )  {

if( $a == 1 ) {
   // do some calcs
} elseif( $a == 2 ) {
    // do some other calcs
}

}
