What is wrong in this code?

<?php
$string = "Copia (3) di Copia (99) di unita";
$val = "Copia (99) di unita";
if (eregi("Copia \(+[0-9]+\) di ".$val,$string))

$vara = explode("Copia (",$string);
$vara = explode(")",$vara[1]);
var_dump($vara);
$maxim = $vara[0];

The pattern here is
"Copia \(+[0-9]+\) di Copia (99) di unita"
the problem is the unescaped parenthesis. simple parenthesis have a special
meaning in regular expressions, they indicate a subpattern. It should be
"Copia \([0-9]+\) di Copia \(99\) di unita", ie. $val should be "Copia
\(99\) di unita".

This could be done easier using the subpatterns you've accidently
discovered. Like:
>
if(preg_match("#Copia \(([0-9]+)\) di Copia \(99\) di unita#", $string,
$matches))
$maxim = $matches[1];
