如何用PHP中的空字符串替换？myuser = number

Question

How can I replace a string containing a lot of ?myuser=12122 ?myuser=5457 ... with empty string so that it doesn't show ?myuser=number inside the string?

I think I should use regex?

Answer 1

是，

 preg_replace('~\?myuser=\d+~', '', $string);

Answer 2

The question mark is a special character in regular expressions, so you must quote it. Apart from that, it's quite straight forward:

$result = preg_replace('/\?myuser=[0-9]+/', '', $source);

Answer 3

$str = preg_replace("/\?myuser=(\d+)/iU","",$yourstring);
