Does not declare variable when used in preg_match function call

[flip111]

php

if (! preg_match('some regex here', $subject, $regs)) {

zephir

if !(preg_match("some regex here", subject, regs)) {

this will crash zephir because regs was not declared and initialized before.

fix

var regs;
let regs = null;
if !(preg_match("some regex here", subject, regs)) {
