it's treating a string as a character array - it's documented somewhere in the manual, can't remember where though :( - not long ago someone was saying that the new way it to use curly-brackets, but square brackets still work for backwark compatibility.

A friend of mine showed me this code recently. function firstLogin_string() { mt_srand(make_seed()); $pool = "AaBbCcDdEeFfGgHhIiJjKkLlM"; $length = 26; for($i=0; $i < $length; $i++) { $key .= $pool[mt_rand(0,strlen($pool)-1)]; } return $key; } look at the for loop. $pool is not an array but is being treated as such and the key happens to be the position in $pool and it'll take that letter and save it to $key. I've never seen this done before. What is this method called and what other neat tricks can you do in respect to this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
