[SOLVED] simple noob question

[SergeantFlash]

I have this code inside a php file and I was wondering if I wrote it the right way, since I'm not quite sure how to check the opposite of something (like a Boolean - true/false):

if (! @is_numeric($pkills)) {
echo( "$pkills is an improper value for kills");
exit();
}

Yes that is correct. is_numeric returns true or false and ! means NOT.

Why do you have the @ there?

[SergeantFlash]

okay, thanks

Wouldn't this be a bit better coding?

if (!is_numeric($pkills)) {
die ($pkills." is an improper value for kills");
}

^^ maybe he just wants to echo it and continue the script execution. so, no.

 

ps, dark finally got an avatar!

Accomplishes the same thing.  But you don't always want to kill the script for something like that (especially a form).  That was directed at the thread starter btw.

 

P.S: I finally got around to making an avatar for this forum.  Wonderful, right? xD

 

EDIT: Someone noticed.  Sick.

Thanks again, I'm very knew to PHP so I'm not sure about to best practices for writing the code. The code is just for a small game I'm making with Flash CS3, when the game ends, the user can submit their score (after writing their name), and I just want to make sure the data received by the php script for kills is actually a numeric string and hasn't been tampered with. So, obviously, if the data for kills isn't actually a number, then I want the script to stop and not insert the data into my database table (mySQL).
