[RESOLVED] File Extension

[thekidscareya]

I have the following code:

$local_image_name = $_FILES['file']['name'];

// Some code here to get a number

$image_name = $row['id'].$image_ext;

I have $row['id'] set already (it will return a number). But how do I get the $image_ext (extension of the image eg: .gif, .jpg, etc.)?

I don't want to use $_FILES['file']['type'] because then I would have to set all the mime types with a extension.
Eg:
text/html would have the extension of .html, etc.

Thanks.

$extentie = substr($files[$i],-3);

im assuminig that your using $extentie as $image_ext and $files[$i] as $local_image_name
(i used http://us3.php.net/substr)

Also, what if the image has an extension like .jpeg and not .jpg

[leatherback]

Well, you could use str_pos to find the dot, and the determine wether it is a 3 or 4 letter extention

i dont understand...it will only return the location of the period in the ext...and not whether the ext is 3 or 4 letters...can you post an example of how to use that?

sorry for my n00bieness

$ext = substr(strrchr($local_image_name, '.'), 1);
