更好的方法来验证PHP中的URL [英] Better way to validate a URL in PHP

问题描述

我一直在阅读堆栈溢出的各种帖子，试图找到一个理想的方式来验证在PHP中的URL。我的研究已经提出了三种可能的解决方案，但是，没有一种是理想的。

提到的三个方法是正则表达式， filter_var（$ url，FILTER_VALIDATE_URL）和 parse_url （）。第一种方法的问题已经众所周知，最全面的验证正则表达式我可以找到跨页面。内置到PHP过滤扩展中的filter_var函数似乎有错误，比如将http：// ...这样的url视为有效。 parse_url方法使用的是从未用于URL验证的函数，因此不能依赖于此任务。

有没有关于PHP中的URL验证的其他选项，我可能错过了？

跨越页面）额外的正则表达式检查你不认为被覆盖的情况吗？

I've been reading various posts on Stack Overflow to try and find an ideal way to validate a URL in PHP. My research has come up with three possible solutions, however, none of them are ideal.

The three methods mentioned are regex, filter_var ($url, FILTER_VALIDATE_URL) and parse_url (). The problems with the first approach are already well known, and the most comprehensive validation regex I could find spanned pages. The filter_var function built into the PHP filtering extension appears to have faults, such as treating a url like http://... as valid. The parse_url method is using a function that was never intended for URL validation and therefore can't be depended on for this task.

Are there any other options regarding URL validation in PHP that I may have missed?

解决方案

How about you combine filter_var (which basically is a regex check that spans pages) with additional regex check for cases you don't think are covered well by it?
