正则表达式在PHP中的任何网址或链接 [英] regex any urls or links in php

问题描述

我有正则表达式来捕获php中的任何url：

I have that regex to catch any url in php :

((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+@)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%@.\w_]*)#?(?:[\w]*))?)

但它没有抓到完整的网址.. ...例如

but it didn't catch the full url ..... for Example

此处：

它只捕获：

http://v12.lscache6.c.youtube.com/videoplayback?app=youtube_gdata&devkey= AX8iKz393pCCMUL6wqrPOZoO88HsQjpE1a8d1GxQnGDm&安培; EL =视频&安培; UPN = 0K3DA3wYhjI&安培; uaopt =无保存&安培;源= YouTube和安培; ITAG = 18和ID = ab59b1e9554eca6d&安培; IP = 0.0.0.0&安培; ipbits = 0&安培;到期= 1339342342&安培; sparams = ID

那么我需要什么来捕捉完整的网址？

So what do I need to catch the full url?

推荐答案

你需要在正则表达式中添加一个昏迷字符：

You need to add a coma character in regex:

你的正则表达式已修复：

Your regex fixed:

((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+@)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%@,.\w_]*)#?(?:[\w]*)?))
