Question

I need to remove all occurences of &page=* from a string, where * is a number. How would I do that with regexp(?)

So far I’ve been using,

$this->targetpage = str_replace('&page='.$this->page, '', $_SERVER['REQUEST_URI']);
echo .$this->targetpage;

Also a bonus would be to not have to include the &, as the page=something could also be after the “?”

Answer 1

$this->targetpage = preg_replace('~((?<=\?)page=\d+&?|&page=\d+)~i', '', $_SERVER['REQUEST_URI']);
