javascript - Showing file icons based on file extension -

i'm making table of uploaded files: file, name, extension (in php connection ms sql server). add on icon to every of files based on extension. find 3 option how can it: 1. best - load somehow user default icon , somehow connect them files 2. - load somehow webpage list of icon , somehow connect them files 3. bad - put icons folder , load file

i know how third option can't search 10 icons because there extension isn't in folder (like jpeg different jpg).

could tell me how can better solution number 3? can in php or js/jquery, doesn't metter.

try thing this:

if(ext == 'jpg' || ext == 'jpeg') {     $image_name = 'image.jpg';   } if(ext == 'doc' || ext == 'docx') {     $image_name = 'doc.jpg';     } 

and make else unknown icon
