Map the image type enum to file extension:
$extensions = array(
    IMAGETYPE_GIF => "gif",
    IMAGETYPE_JPEG => "jpg",
    IMAGETYPE_PNG => "png",
    IMAGETYPE_SWF => "swf",
    IMAGETYPE_PSD => "psd",
    IMAGETYPE_BMP => "bmp",
    IMAGETYPE_TIFF_II => "tiff",
    IMAGETYPE_TIFF_MM => "tiff",
    IMAGETYPE_JPC => "jpc",
    IMAGETYPE_JP2 => "jp2",
    IMAGETYPE_JPX => "jpx",
    IMAGETYPE_JB2 => "jb2",
    IMAGETYPE_SWC => "swc",
    IMAGETYPE_IFF => "iff",
    IMAGETYPE_WBMP => "wbmp",
    IMAGETYPE_XBM => "xbm",
    IMAGETYPE_ICO => "ico"
);

If you are working with Images only and you need mime type (e.g. for headers), then this is a fast and reliable technique:

<?php
$file
= 'path/to/image.jpg';
$image_mime = image_type_to_mime_type(exif_imagetype($file));
?>

It will output true image mime type even if you rename your image file.

I was looking to detect the format of images, Im not sure if this is the best way but it works for me.

<?php
$filename
= 'http://static.php.net/www.php.net/images/php.gif';
$size = getimagesize($filename);

switch (
$size['mime']) {
    case
"image/gif":
        echo
"Image is a gif";
        break;
    case
"image/jpeg":
        echo
"Image is a jpeg";
        break;
    case
"image/png":
        echo
"Image is a png";
        break;
    case
"image/bmp":
        echo
"Image is a bmp";
        break;
}
?>
