Function by reference or value

[rastkocvetkovic]

Could somebody write a solution that would get the parameters by reference so that the code:

<?
$string = &quot;this is cool&quot;;

function by_reference($something) {
$something = &quot;this is new&quot;;
}

by_reference($string);

echo $string;

?>

Would output &quot;this is new&quot; and not &quot;this is cool&quot;.

I assume that all functions in PHP get parameters by value, how to transfort the $something to C++ style var $something. Thank you for answers!

I'll answer it myself. The difference is in &$something!
<?
$string = &quot;this is cool&quot;;

function by_reference(&$something) {
$something = &quot;this is new&quot;;
}

by_reference($string);

echo $string;

?>
This outputs &quot;this is new&quot;!
Hope this helps anyone else but me
