Simple spaces problem.

[Anon]

Okay, in my username/password system, I've blocked out every way imaginable to have two of the same usernames; except for one possibility.

How can I stop (for example) someone from registering: John Doe
And then someone else registering: J o h n D o e

?

Any help would be greatly appreciated!

use the str_replace-function, and replace " " with ""...

Read about it <a href=http://www.php.net/manual/function.str-replace.php>here</a>

Good Luck...

You can strip spaces from the 2 strings then compare them:

$str1="John Doe";
$str2="J o h n D o e";

if ( ereg_replace(" ","",$str1)==ereg_replace(" ","",$str2) {
echo "Same strings<br>\n";
} else {
echo "Different<br>\n";
}

If you have the names in a MySQL database try this:

SELECT REPLACE( name, ' ', '' )

This will give you all the names with the spaces removed.

Take the name supplied by the user and

$short_name = str_replace( $name, ' ', '' );

This will give you the name in a short version.

Then do a case insensitive compare:

$trueORfalse = eregi( $dbname, $short_name );

This will give true if you find a match.

Hope this works,
