如何在 PHP 中将 www.mydomain.com/page/user/756890 转为 www.mydomain.com

Question

How could I replace the URL of a string from this:

798| 451.263.160.11| CONNECT | http://www.mywebsite.com/pages/user/678976546789 | China | 22 min

To this in PHP:

798| 451.263.160.11| CONNECT | http://www.mywebsite.com | China | 22 min

Thanks guys :)

[NOTE: The text is from a file]

Answer 1

I'm not sure what you mean by "register file", but it looks like you're trying to do a regex replacement .

$input = '798| 451.263.160.11| CONNECT | http://www.mywebsite.com/pages/user/678976546789 | China | 22 min';

$search_for = 'http://www.mywebsite.com';

$output = preg_replace('/' . preg_quote($search_for, '/') . '([^ ]+)/', $search_for, $input);

The code above will search for the string you provide, and remove all characters until the next space.

You can find out more about regex in PHP using the manual:
