Works here:
glopes@nebm:~/php/php-src$ php -v
PHP 5.3.10-dev (cli) (built: Feb 2 2012 11:31:13)
Copyright (c) 1997-2012 The PHP Group

glopes@nebm:~/php/php-src$ php
<?php
$r='/^(?P<foo>\w+)\/(?P<bar>\d+)\/$/u';
var_dump(preg_match($r,'test/3423/',$m), $m);
int(1)
array(5) {
[0]=>
string(10) "test/3423/"
["foo"]=>
string(4) "test"
[1]=>
string(4) "test"
["bar"]=>
string(4) "3423"
[2]=>
string(4) "3423"
}
I suspect that, if anything, this has been an PCRE change. Try recompiling PHP with the bundled PCRE
(--with-pcre-regex=BUNDLED, if I'm not mistaken).

Your expression trigger a warning too.

But this expression works fine in the PHP 5.3.x (and 5.2.x).
And works fine without the Modifier "u".
Why does not works fine in PHP 5.4?

Your expression is wrong. Version 8.02 of PCRE, which you're using, gives that rather cryptic
error, but more recent versions, including the one bundled with PHP say:
Warning: preg_match(): Compilation failed: unrecognized character after (?P at offset 4 in - on line
3
Probably you want something like:
<?php
$r='/^(?P<foo>\w+)\/(?P<bar>\d+)\/$/u';
var_dump(preg_match($r,'test/3423/',$m), $m);

Description:
------------
I am not good at english.
A warning: preg_match(): Compilation failed: unknown option bit(s) set at offset
0
OS: MacOSX Lion 10.7.2
Web Server: apache 2
PHP : 5.4.0
PCRE (Perl Compatible Regular Expressions) Support: enabled
PCRE Library Version: 8.02 2010-03-19
By the way: the php 5.4.0 released is stable or not ?
thanks.
Test script:
---------------
<?php
$r='/^(?P\w+)\/(?P\d+)\/$/u';
var_dump(preg_match($r,'test'));
Expected result:
----------------
What does the warning mean ?
The preg_match should be return 0 without warnings.
Actual result:
--------------
Warning: preg_match(): Compilation failed: unknown option bit(s) set at offset 0
in /Users/zhangyowei/Web/lieqee/test.php on line 4
bool(false)
