PHP: Getting the File Type of an Image
Monday, June 8th, 2009I am working on an image upload plugin that uses JQuery. I am using PHP on the backend. I have found that there are multiple ways to use PHP to get the file extension of an image.
PathInfo
PathInfo is probably the most common way get information about a file.
$path_parts = pathinfo('http://grasshopperpebbles.com/photogallery/thumbs/pic1.png'); echo $path_parts['dirname']; //output: http://grasshopperpebbles.com echo $path_parts['basename']; //output: pic1.png echo $path_parts['extension']; //output: png echo $path_parts['filename']; //output: pic1 |
GetImageSize
Although I have used PHP’s getimagesize to get the dimensions of an image, it can also be used to get other information (to include the file type):
list($width, $height, $type) = getimagesize('pic1.png'); echo $type; //output: png |
End
Recently, I stumbled upon a new way to get the file extension:
$file_name = current(explode('.', 'pic1.png')); $ext = end(explode('.', 'pic1.png')); echo $file_name; //output: pic1 echo $ext; //output: png |
I’m sure there are other ways to use PHP to get the file type as well.
