php - How to catch filetypes in malformed URLs -


just wondering how can extract or match specific file type, since there lot of malformed urls , directories.

so need regex match real ones.

http://domain.com/1/image.jpg <-match .jpg http://domain.com/1/image_1.jpg/.gif <-match first .jpg http://domain.com/1/image_1.jpg/image.png <-match first .jpg http://domain.com/1/image_1.jpg <-match .jpg http://domain.com/1/image.jpg.jpeg <-match first .jpg http://domain.com/1/.jpg <-not match http://domain.com/.jpg.jpg <- not match /1/.jpg <-not match /.jpg.png <-match first jpg /image.jpg.png <-match first jpg

i'm trying piece of code:

preg_match_all('([a-za-z0-9.-_](jpg))i', $url, $matches);

any ideas?

preg_match('(^(http://domain.com/\w.*?\.jpg))i', $url, $matches);

this match start of string first .jpg. filename part must start letter, number, or _.
