URL的PHP​​验证/正则表达式 [英] PHP validation/regex for URL

问题描述

我一直在寻找URL的简单正则表达式，有人能用得起吗?我没有在zend框架验证类中找到一个，并且看到了几种实现.

I've been looking for a simple regex for URLs, does anybody have one handy that works well? I didn't find one with the zend framework validation classes and have seen several implementations.

推荐答案

我在一些项目中使用了此方法，我不认为我遇到了问题，但我确定它并不详尽:

I used this on a few projects, I don't believe I've run into issues, but I'm sure it's not exhaustive:

$text = preg_replace(
  '#((https?|ftp)://(\S*?\.\S*?))([\s)\[\]{},;"\':<]|\.\s|$)#i',
  "'<a href=\"$1\" target=\"_blank\">$3</a>$4'",
  $text
);

最后，大多数随机垃圾是用来处理句子中的http://domain.com.之类的情况(以避免匹配尾随时间段).我敢肯定它可以清除，但因为它起作用了.我或多或少只是将其从一个项目复制到另一个项目.

Most of the random junk at the end is to deal with situations like http://domain.com. in a sentence (to avoid matching the trailing period). I'm sure it could be cleaned up but since it worked. I've more or less just copied it over from project to project.
