PHP regex replace phrase + number

Question

My string is

"http://exanmple.com/katalogas/?is_search=1&type=list&filter=search_1&activity=&activity_id=&activity=langai&activity_id=&region_id=-2&page_no=2"

I want replace from string all page_no=2 number can change, phrase is static page_no

What I try:

/\&page_no=[0-9]\b/i

You can match this regex:

/(?<=\?)page_no=\d+&|&page_no=\d+\b/i

Code:

$url = preg_replace('/(?<=\?)page_no=\d+&|&page_no=\d+\b/i', '', $url);

You should add an optional & at the end of the pattern to avoid && or ?& when page_no isn't the last parameter.

Thanks, yes I realized that a & also need to be removed, edited now.
