PHP substr Query - Cropping URL

Question

I currently have the string: "/en/sports/football/"

How do I substr this string to achieve:

"/sports/football/"

Many thanks for any pointers.

Answer 1

Well, lets take a look: http://php.net/manual/en/function.substr.php

The method signature looks something like this:

string substr ( string $string , int $start [, int $length ] )

If length is omitted, the substring starting from start until the end of the string will be returned.

So I guess we could do something like this to get characters 3 and onward.

substr("/en/sports/football/", 3);

Answer 2

在'/'上explode() ，丢弃不需要的目录，然后在'/'上implode()
