正则表达式只捕获JPG图像

Question

I have this regex in PHP:

$regex = '/<img[^>]*'.'src=[\"|\'](.*)[\"|\']/Ui';

It captures all image tag sources in a string, but I want to only capture JPG files. I've tried to mess around with (.*) but I've only proven that I suck at regex... Right now I'm filtering the array but feels too much like a hack when I can just do it straight up with a proper match.

Answer 1

Try this:

$regex = '/<img ([^>]* )?src=[\"\']([^\"\']*\.jpe?g)[\"\']/Ui';

I also removed the extra | in the character classes that was not needed.
