PREG_MATCH found chars in pattern?

Question

Is there a way to use the found occurrence within pattern? i.e.

$string='number23 cat99 dog23 car66';

for example, i want to find words that has number 23.... this doesnt work:

preg_match('/number(\d{2}) (.*?)%1/si', $string,  $new);

Yes. Twice. Just read it again and it still just looks like a code request. One with unclear requirements at that. — Biffen, May 25 '16 at 17:42

Not sure I well understand your need, but how about using preg_match_all:

preg_match_all('/([a-z]+23)\b/i', $string, $matches);

This will match number23 and dog23
