preg_replace() remove things between but ignore rest

[SharkBait]

So how do I go about using preg_replace() to remove a portion of a string and ignoring the rest of it?

 

String: [http://this.is.my.site.com/stuff/funn] this is cool!

 

so that it only returns

 

this is cool!

 

I can't seem to get the regex pattern right

More example data please.

Anytime something shows up with [http://afdasdfsaf]

I guess anytime a URL shows up within square braces, i want to remove the square braces and the contents within them

 

I just want the the [http://afdasdfsaf] removed. Sorta like BBCode, but it isnt

$result = preg_replace('/\[[^]]*\]/', '', $subject);
