upload script question

All,

I'm currently working on a photo upload script using PHP. Everything appears
to work fine for the most part, however it appears that some of my images do
not show up with any type... so, I'm running my script using:

if ($_FILES['imagefile']['type'] == "image/jpeg" ||
$_FILES['imagefile']['type'] == "image/pjpeg")

However, some photos have a type of nothing... so, though the file is .jpg,
the upload will fail as it's not getting the type of jpeg out of the $_FILES
array. I've tried opening the actual images that aren't working and saving
them as .jpg to make sure something didn't go bad on the original save, but
have the same problem.

Anyone seen this or know of a fix?

Man, I'm stuck here - Any ideas from anyone?

Google, as always, is Your Friend.

I've never posted for help on a newsgroup before an exhaustive search on
google and my other normal resources.

This solution unfortunately brings me to the same problem - Is it possible
these images are just bad? If so, is there a way to "repair" them, or work
with them anyways?

The mime type in $_FILES[]['type'] contains data provided by the client, so
it isn't necessarily reliable, any it may not exist at all.

Instead, try using mime_content_type() to check the actual uploaded file.

For whatever reason, I can't use this function with our host. PHP 4.4.1
should be compadable, but it doesn't work. Any other possible ways?

Also - to Mr. Anonymous - Your script is only validating by file type, I was
able to save a text file as .jpg and upload it without problems. Plus,
spamming sucks :\

Ok, I'm an idiot. The problem with my script not finding the file type was
because I set my MAX_FILE_SIZE too low, and the transfer of the file would
fail from one page to the next, therefor there was obviously no file type to
get. Live and learn - thanks for the help guys :)

someone's already done the footwork by making classes that examine the file
headers to detect the filetype.

and from another post I learned about mime_content_type('php.gif')
