Topic awaiting preservation: User Registration Script...

Hello,

I need some help here. I am writing a script which invloves a User Registration. Ive made it so the names and other information is in a text file. Users can sign up, but theres one problem. Two of the same names can be registered (ie: brian, brian). I would like it so that the user can register with the same name as an already existing member. I have attempted to make it work, but i cant. So thats why im coming here.

Here is what im trying to do:
<BLOCKQUOTE><FONT face="Verdana, Arial">code:</font><HR><pre>$file = file("users.txt");
while(list(,$value)=each($file)){
list($name, $password2) = explode("

just a wild guess, but after you explode() there might be some whitespace around $name... so try to replace strtolower($name) with strtolower(trim($name))

so long,

Okay, that did not work, but ive got it. I just put all the names in an array and used preg_grep() to check if the $user exists in the array. Heres the code:

<BLOCKQUOTE><FONT face="Verdana, Arial">code:</font><HR><pre>
function valid_name($usn, $arr) {
return preg_grep('/^' . preg_quote($usn, '/') . '$/i', $arr);
}

$file = file("user.txt");
foreach ($file as $c) {
list($name, $password2) = explode("

You shouldn't need the preg_grep (since you're not using any of the features of a reg_exp) you can just use in_array;



.:[ Never resist a perfect moment ]:.

yeah, but i wanted it to be case-insensitive. I found that little snippet in the php.net manual for in_array i believe. So i gave it a try and it worked out great.

yep:

case-insensitive version of in_array:

function is_in_array($str, $array) {
return preg_grep('/^' . preg_quote($str, '/') . '$/i', $array);
}

located at the bottom of the manual.
