Determining file types.

I know how to get them.. I want to only allow gif/jpeg.

How can I run a checker to do this? It should be simple, but I'm a newbie :-p

if($extension == "jpg" || $extension =="gif") {
    // do stuff;
} else {
    // not valid file stuff;
}

Hope this helps,

How would I define $extension?

$extension = $_FILE['file']['type']; ? Cause wouldn't that assign it to be image/gif or image/jpeg?

I was thinking you could get it with the substr command from the filename. something like:

$extension = substr($filename, -3);

Obviously you would need the filename in a variable, I am not sure how you are going about that but I am sure you can figure that part out 😃

Wanna be real hard-core? Are you on 'Nix?

<?php

$type=(`file $filename`);

if (!(stristr($type, "JPEG") || stristr($type, "GIF"))) {

echo "Filetype not allowed, |@m3r...
    <br>";

}
