trouble with preg_match

[Thorsten Walenzyk]

Hi all,

I'm pretty new to PHP. So far I know regular expression only from Perl

I've written a perl script which I now want to port to PHP. It works in
PErl, but gives my a headache in PHP.

I have a line like this:
"329:47 InitGame:
\.Admin\xxx\.We bsite\www.yyy.de\g_gametype\hq\gamename\Call of
Duty\mapname\mp _ship\protocol\ ..."
I want to get the time at the beginning of the line. Further I need the text
between "gametype\" and "\gamename" ("hq" in this case) and the text
between "mapname\" and "\protocol" ("mp_ship").

The reg ex in Perl looks like this:
if ($line =~
m/(\d+:\d+)[\s]*InitGame:.*?_g ametype\\(.*?)\ \.*?mapname\\(. *?)\\/) {...

It took me quite long time, to find this ugly construct in PHP:
$match_initGame = '(\d+:\d+)\s*In itGame:.*?_game type' . preg_quote("\\" )
.. '(.*?)' . preg_quote("\\g amename") . '.*?' . preg_quote("\\m apname\\") .
'(.*?)' . preg_quote ("\\");
if (preg_match("/$match_initGame/", $line, $matches ) ) {...

Is there is any better way to solve my problem?

Thanks a lot, Thorsten

if (!preg_match($r x, $text, $matches)) {

}

unset($matches[0]);
print_r($matche s);

Thanks Pedro.

It is somehow strange to use 4 backslashes, but it works.

Thanks, Thorsten

You may want to know the difference between single quote and double
