Exclude whole word using regexp

I'd like to exclude word user and gallery using regular expression.

^/(?!user|gallery)([a-z0-9_-]{3,64})$

My regexp also excludes words like mygallery (in which gallery is a substring). I want to have mygallery included.

Thanks a lot in advance.

Try this :

$str = "mygallery and gallery user and username";
echo preg_replace("/\bgallery\b|\buser\b/","",$str);

Output :

mygallery and and username

Your regex should already accept mygallery, but it would reject username. Add anchors to make sure it doesn't:

^/(?!user$|gallery$)([a-z0-9_-]{3,64})$
