preg replace

Simple example please.

[gosman]

Hopefully someone can help.

I'm a complete newbie to PHP I'm trying to find a preg_replace example using wildcards that makes sense.

Here's what I'm trying to acheive.

I have a string of text formatted as follows.

someurl-c*.htm

what I want to replace is the -c*.htm so I'm left with just

someurl

c* is a wildcard could be c1, c2, c1000, etc..

I have tried to figure this out before posting but all examples I can find are a bit complex. Maybe it's just late :-)

$subject="some-url-csldkfj.htm";
$subject = preg_replace('/(-c)(.*)/','',$subject);

(-c) says look for hyphen followed by the letter 'c'.
(.*) says 'everything after that'.

Whatever's not included in the match won't be replaced, and you're replacing the matched parts with nothing, so the result:
$subject="some-url"
