PHP Bug Type: PCRE related
Bug description: (?{CODE}) pattern not recognized, won't compile expression
Description:
------------
The (?{CODE}) regular expression has been in Perl since <= 5.005, and
the PHP documentation for PCRE says that it's current as of 5.005. This
functionality does not appear to be functional in PHP 5.2.9.
Reproduce code:
---------------
<?
$pattern = '/^(?{ $d=0
})(?:\((?{$d++})|\)(?{$d--})(?(?{$d<0})(?!))|(?>[^()]*))*(?(?{$d!=0})(?!))$/';
$pattern_simple = '/^(?{$d=0})\(/';
$subject = '((I)(like(pie))!)';
echo "result: ".preg_match($pattern, $subject)."<br/>";
echo "result_simple: ".preg_match($pattern_simple, $subject)."<br/>";
?>
Expected result:
----------------
I'm not claiming that the regular expressions should produce a match,
but they should compile and be evaluated, and thus return either a 0 or
a 1.
Actual result:
--------------
Warning: preg_match() [function.preg-match]: Compilation failed:
unrecognized character after (? or (?- at offset 2 in __FILE__ on line
__LINE__
