php - regex find input value -

-

the string is:

<input type="hidden" name="billing[address_id]" value="34543" id="billing:address_id" />

how can input value string? tried code:

preg_match('/<input type="hidden" name="billing[address_id]" value="(.*?)" id="billing:address_id" \/>/mis', $html, $results);

your regex correct.. escape [ , ] @ address_id.

preg_match('/<input type="hidden" name="billing\[address_id\]" value="(.*?)" id="billing:address_id" \/>/mis', $html, $results);
