Preg_replace Help

[djtozz]

Hello,

 

Following code retrieves the file extension from a url

 

				$words=preg_split("/[_\.\-]/",$words);
				$lastword=array_pop($words);
				if($lastword=="html") array_pop($words);
				$words=implode(" ",$words);
				$words=preg_replace("/\s{2,}/"," ",$words);
				$caption=mysql_real_escape_string($words);
                                        unset($words);

 

The IF statement removes the ".html" extension from the url.

I would like to do the same for ".htm" extensions.

 

I'm not sure which pattern to use.

Hi djtozz,

 

Could you not use the OR operator?

 

i.e.

 

if($lastword=="html" || $lastword=="htm") array_pop($words);

 

Hope this helps.
