[SOLVED] checking filetypes

[Ninjakreborn]

I had a file handling program I built awhile back but ended up losing over time.  Now I have this half system to validate filetypes.  Is there a good/proven method that is really powerful that anywhere here uses to validate there filetypes.  Just a specific method that you have used for a long time, and you know work's really well.  I am going to come up with my own again, I just want some idea's on how to formulate it.  Thanks?

If it's just images and you're using PHP >= 4.3.0 then just use getimagesize() as this returns the mime-type of the image.

So something like.

<?php
$accepted_types = array("gif",
                                   "jpg",
                                   "jpeg",
                                   "bmp");
if (!get_image_size($filename, $accepted_types) {
// not allowed
}else {
// do file stuff
}
?>

Is that about along the lines of what you mean?

$i=@getimagesize($_FILES['logo']['tmp_name']);

if (($i[2]==1) or ($i[2]==2) or ($i[2]==3)) {

# OK

} else {

# FAILS

}

I found this example.  Is this flawless or is there something else that need's to be done with it?

Got it

$i=@getimagesize($_FILES['logo']['tmp_name']);

if (($i[2]==1) or ($i[2]==2) or ($i[2]==3) or ($i[2]==6)) {

 

Thanks

Do I check for

'name' or 'tmp_name'

When I run this?

Nevermind, I got it again.
