Get image extension

Question

I want get uploaded image extension.

As I know, best way is getimagesize() function.

but this function's mime, returns image/jpeg when image has .jpg or also .JPEG extension.

How can get exactly extension?

Answer 1

you can use image_type_to_extension function with image type returned by getimagesize:

$info = getimagesize($path);
$extension = image_type_to_extension($info[2]);

Answer 2

$ext = pathinfo($filename, PATHINFO_EXTENSION);

Answer 3

You can also use strrpos and substr functions to get extension of any file

$filePath="images/ajax-loader.gif";

$type=substr($filePath,strrpos($filePath,'.')+1);

echo "file type=".$type;

output: gif

if you want extension like .gif

$type=substr($filePath,strrpos($filePath,'.')+0);

output: .gif

Answer 4

$image = explode(".","test.file.hhh.kkk.jpg");
echo end($image);

Answer 5

One more way to do it:

$ext = strrchr($filename, "."); // .jpg

Answer 6

$file_ext = pathinfo($_FILES["file"]["name"], PATHINFO_EXTENSION);

or to make it clean

$filename= $_FILES["file"]["name"];
$file_ext = pathinfo($filename,PATHINFO_EXTENSION);
