Changing it to (?P>name) or (?&name) works as expected (see http://perldoc.perl.org/perlre.html#PCRE%2fPython-Support and elsewhere on the same page). The reference to (?P&name) needs to be changed to (?&name). Test script: --------------- <?php var_export(preg_match('/(?<foo>a)(?P>foo)/', 'aa')); // Good print("\n"); var_export(preg_match('/(?<foo>a)(?&foo)/', 'aa')); // Good print("\n"); var_export(preg_match('/(?<foo>a)(?P&foo)/', 'aa')); // Bad ?> Actual result: -------------- 1 1 Warning: preg_match(): Compilation failed: unrecognized character after (?P at offset ... ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62237&edit=1
