It is *very* expensive to use eval, expecially when this has been
said:
If eval() is the answer, you're almost certainly asking the
wrong question. -- Rasmus Lerdorf, BDFL of PHP
Here are a couple alternatives:
function argbyref(&$args) {
$args['arg'] = 'changed';
}
$args['arg'] = 'not changed';
argbyref($args);
function argwitharray($args) {
$args['arg'] = 'changed';
}
$arg = 'not changed';
argwitharray(array('arg' => &$arg));
