Comparing match results (preg_match)

[TomatorCZ]

Peachpie returns wrong offsets in matches.

Implication:
WordPress plugin GutenSlider doesn't work properly (issue #99).

Example:

<?php
preg_match('/(?P<fooname>foo)?(bar)/', 'bar', $matches, PREG_OFFSET_CAPTURE);
$is_fooname = isset( $matches['fooname'] ) && -1 !== $matches['fooname'][1];
var_dump($is_fooname);

Expected value:
bool(false)
Actual value:
bool(true)
