I use http://www.regular-expressions.info
The site's author also has a book which I would recommend :

Sounds to me like an issue connecting to memcached, possibly DNS-related. How
is the lookup of web1/web2 being performed? Have you tried the lookup on the
server?
Alternatively try connecting to the memcached servers using netcat or telnet -
does that exhibit the same delay?

I have a working socket server in PHP that I wish to improve (allow for more
socket connections). I am running into a limit I can't crack, related to the
max number of incoming socket connections. Using Macports for package
management... I've recompiled PHP with the --enable-fd-setsize=2048 in the port
file) … but I still get the following PHP warning once my socket server tries
to accept more than 1024 clients (800, 900 are okay):
PHP Warning: socket_select(): You MUST recompile PHP with a larger value of
FD_SETSIZE.
It is set to 2048, but you have descriptors numbered at least as high as
1027.
--enable-fd-setsize=2048 is recommended, but you may want to set it
to equal the maximum number of open files supported by your system,
Weird right? Shows I have it set in PHP, so maybe it's a resource limit? But
having changed sysctl.conf, ulimit -a shows:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 2048
pipe size (512 bytes, -p) 1
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 709
virtual memory (kbytes, -v) unlimited
So I should be able to have up to 2048 files (sockets) open, but PHP still
complains. What am I missing? Any ideas what I should try next?

Here:
>> die(preg_filter('/[^:][[:punct:]]/', '', $string));
Did you really want to do this:
preg_filter('/[^:][[:punct:]]/', '', $string) or die("nothing returned\n");
???
See http://php.net/manual/en/function.preg-filter.php "Return values"
as Richard points out preg_filter returns NULL if there are no matched
in a string.
Now this is interesting:
>> $string = "a=10&b[]=20&c=30n°&d=40+:50";
There is a wide character in that string following 30n. The preg
functions sometimes don't deal well with wide characters in my
experience (it's not 100% anyway), you probably need to use the mb_
functions instead.
