PHP preg_match UUID v4 [英] PHP preg_match UUID v4

问题描述

我有一个字符串，其中包含 UUID v4

I've got a string that contains UUID v4

$uuid = 'http://domain.com/images/123/b85066fc-248f-4ea9-b13d-0858dbf4efc1_small.jpg';

我如何使用preg_match()从上面获取b85066fc-248f-4ea9-b13d-0858dbf4efc1值?

推荐答案

$uuid = 'http://domain.com/images/123/b85066fc-248f-4ea9-b13d-0858dbf4efc1_small.jpg';
preg_match('!/images/\d+/([a-z0-9\-]*)_!i', $uuid, $m);

还有

preg_match('/[a-f0-9]{8}\-[a-f0-9]{4}\-4[a-f0-9]{3}\-(8|9|a|b)[a-f0-9]{3‌​}\-[a-f0-9]{12}/', $uuid, $m);

也可以.取自此处，但我不知道不知道我们是否可以依靠它.

works too. Taken from here, but I don't know if we can rely on that.
