Regulars - an optional "stop" character?

Question

PHP

Chet I was tired. In general, there is a line like

text: texttext;text;var=abc;text

So, she could be

text: texttext;text;var=abc

The task is to pull out abc, regardless of whether there is a ; or not. Chet I can't.
I tried like this

'/^text: .*;var=(.*)[;|$]/im'

But I'm doing something wrong.

$string = 'text: texttext;text;var=abc';//'text: texttext;text;var=abc;text';
$regExpWrapper = "/(?:var=)(.*?)(?:;|$)/";
preg_match($regExpWrapper, $string, $matches);
print_r($matches);
