Array help

Hi! I have a login/password file with these kind of values: user1:pass1 user2:pass2 cat:dog love:hate I have opened the file and put it into an array with this code: (thanks to richard lynch from this list for idea and code snippets) $file = file_get_contents('a.htpasswd'); preg_match_all('/(.*):(.*)$/msU', $file, $htpassd); but how do I get it into this format : $users['username'] = 'password' without using a loop? I was thinking something like array_flip or array_splice?? (The reason I dont want to use a loop (for,while) is there can be thousands of user:pass combos in the files and thousands of logins and attempted logins a day) Suggestions/comments/links too are most welcome.
