Works here:

<?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).

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

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:
--------------

0
in /Users/zhangyowei/Web/lieqee/test.php on line 4
bool(false)
