regex - How do I grab last number in a string in PHP?

Question

How can I get 23 instead of 1 for $lastnum1?

$text = "1 out of 23";
$lastnum1 = $this->getEval(eregi_replace("[^* out of]", '', $text));

Answer 1

you could do:

$text = "1 out of 23";
if(preg_match_all('/d+/', $text, $numbers))
    $lastnum = end($numbers[0]);
