Check this out: http://www.php.net/manual/en/functions.arguments.php
Specifically this example:
Making arguments be passed by reference
By default, function arguments are passed by value (so that if you change
the value of the argument within the function, it does not get changed
outside of the function). If you wish to allow a function to modify its
arguments, you must pass them by reference.
If you want an argument to a function to always be passed by reference, you
can prepend an ampersand (&) to the argument name in the function
definition:
*Example 17-6. Passing function parameters by reference*
<?php
function add_some_extra(&$string)
{
$string .= 'and something extra.';
}
$str = 'This is a string, ';
add_some_extra($str);
echo $str; // outputs 'This is a string, and something extra.'
?>
I think that does what you want?
