Summary

0001703: Not all named subpattern matches can be indexed by name in array set by preg_match_all()

Description

preg_match_all() sets the array its third argument is a reference to to a set of matches, which I'll call $matches. When named subpatterns are used, $matches can be indexed by either the subpattern number or name if the subpatterns are named. With Quercus, it appears that the indices named for a subpattern aren't always added to $matches. Here's some example code:

<?php
$text = "<H2>some title</H2>";
$matches = array();
$numMatches = preg_match_all('/<H(?P<level>[1-6])(?P<attrib>.*?'.'>)(?P<header&
gt;.*?)<\/H[1-6] *>/i', $text, $matches);
print_r($matches);
?>

Using PHP 5.2.1 this prints:

Array
(
    [0] => Array
        (
            [0] => <H2>some title</H2>
        )

    [level] => Array
        (
            [0] => 2
        )

    [1] => Array
        (
            [0] => 2
        )

    [attrib] => Array
        (
            [0] => >
        )

    [2] => Array
        (
            [0] => >
        )

    [header] => Array
        (
            [0] => some title
        )

    [3] => Array
        (
            [0] => some title
        )

)

But with Quercus the following is printed:

Array
(
    [0] => Array
        (
            [0] => <H2>some title</H2>
        )

    [1] => Array
        (
            [0] => 2
        )

    [header] => Array
        (
            [0] => 2
        )

    [2] => Array
        (
            [0] => >
        )

    [3] => Array
        (
            [0] => some title
        )

)

The values using numerical indexes are consistent, but Quercus doesn't include the attrib or level index names to $matches while PHP does.
