PHP 4 Default Function Parameter

Question

can I use this syntax under PHP 4 (default function parameter) :

function myFunction($arg1 = 'defaultValue') {}

Thanks.

Actually, I would very much encourage use of default parameters in every function. — thomasmalt

Yes you can. And it can be overwritten like this:

<?php
$var = 'one';
myFunction($var);

function myFunction($arg1 = 'defaultValue') {
echo $arg1;
}
?>

the output would be one
