Determining image type...

[Anon]

if ($image_type == "image/pjpeg")
{
STATEMENTS...
}
elseif($image_type == "image/gif")
{
STATEMENTS...
}

I'm writing an image upload script, and need to determine the extension of the uploaded image.

The above code is supposed to do that.

My question however is, how does $image_type come about in the code? Is it a standard php function?

Thanks.

Did you read this?

What you are looking at is the mime-type that the browser decided to use.
If you want the real filetype you have to look at the filename or even at the fileitself.
