RE: [PHP] Upper and lower case.
is it better to store user names as upper and lower case? should they bee converted to one case? Store it where? It depends if the place you store it in and the comparisons there are going to be case sensitive or not. Most database fields are going to be case sensitive while a PHP comparison will not be. I have a script the checks for names and ... Mark is not the same as mark, or MaRk ... In PHP when you test with an equal to (==) they are not the same. You can use the strcasecmp() function to compare string case insensitively, though. In a general database VARCHAR field, they would be the same. is there a way of making a string into lower case?

Re: [PHP] Upper or Lower Case
Hi Taz, What happens if they type NeO, or NEO, or nEo, or neO (etc)? ;) Also, if you're using this in a large application (or intend to in the future), are you going to type out all of the names as you have done with the neo example? Bjorn's method is much better, and you're better off getting into good practice early. James Tarrant Costelloe [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: [PHP] Upper or Lower Case
Also keep in mind that sometimes spaces find their ways into the string
and using trim() will get rid of them. Something like :
if (strcasecmp('neo',trim($name)) == 0) {
echo 'You chose our Neo line of goods, way to go!';
}
Not to say spaces randomly attach to strings :-) but to be safe, I'm
usually a trim freak. I Love to trim!
Regards,
Philip

Re: [PHP] Upper or Lower Case
I must agree with Don that strcasecmp is the best way
to go. Combined with the 'trim' function this is
completely foolproof.
Thanks, Don!
