php5-pcre utf-8 problems

Hi all,
I'm trying to get php5-pcre working with utf-8 support. Here is the test case:

if (@preg_match('/\pL/u', 'a') == 1) {
echo "PCRE unicode support is turned on.\n";
} else {
echo "PCRE unicode support is turned off.\n";

And the result is "PCRE unicode support is turned off". I have the following installed:

# pkg_info |grep pcre
pcre-7.8 Perl Compatible Regular Expressions library
php5-pcre-5.2.6_2 The pcre shared extension for php

And this is the output from pcretest -C:

PCRE version 7.8 2008-09-05
Compiled with
UTF-8 support
Unicode properties support
Newline sequence is LF
\R matches all Unicode newlines
Internal link size = 2
POSIX malloc threshold = 10
Default match limit = 10000000
Default recursion depth limit = 10000000
Match recursion uses stack

I'm using FreeBSD 6 stable. This is the output from uname:

FreeBSD xxxx 6.3-STABLE FreeBSD 6.3-STABLE #2: Mon Aug 4 16:50:44 EEST 2008

I tried to reinstall pcre and php5-pcre, but the result is the same. Any suggestions are welcome.

Tanks in advance !
That is strange. Did you install from ports? Mine works:

$ php -q
if (@preg_match('/\p{L}/u', 'a') == 1) {
echo "PCRE unicode support is turned on.\n";
} else {
echo "PCRE unicode support is turned off.\n";
PCRE unicode support is turned on.

I modified /etc/login.conf inserting the following line in default section:


Then rebuild with:

cap_mkdb /etc/login.conf

After that i recompiled the php with:

portupgrade -Df php5*

And the result is still the same:

# php test.php 
PCRE unicode support is turned off.
Obviously the problem it's not into the port, because with the package the result is the same. It's something else ..
# make -C /usr/ports/lang/php5 showconfig
===> The following configuration options are available for php5-5.2.6_2:

===> Use 'make config' to modify these settings
Perhaps this is a silly question - but... (if you are using mod_php5) did you restart apache after rebuilding PCRE extension?
Well, the usual suspect, multibyte zend is on. Next up: mbstring extension is loaded? And the internal encoding:
php -i |grep internal_encoding
did you restart apache after rebuilding PCRE extension?

Yes I did.

php -i |grep internal_encoding
iconv.internal_encoding => ISO-8859-1 => ISO-8859-1
mbstring.internal_encoding => ISO-8859-1 => no value
Solved (for me at least!)

I know its old - Google doesn't care though! Try running your test script on the command line i.e php xxx.php and see if that works. I found with apache-2.2.21 and php5-5.3.8 I needed to add
AddDefaultCharset utf8 to httpd.conf
to httpd.conf.
