Removing part of a string that changes

PHP
1

Hello,

I’m not sure that this is possible, but I have a url which I’d like to check for the portion “page=1&” (see below)

“list_ungraded_review_questions_students.php?page=1&chapter_name=Quadratic_Functions&section_name=multiplying_binomials_by_geometry”

If the URL has this string, then I’d like to be able to get rid of that part of the URL. The problem is that the number portion of the page= won’t be known ahead of time. I thought about chopping up the URL into pieces, removing page=# then gluing back together; but the problem is that the number could be 1 or more digits. Might there be a clean approach to this issue?

Thank you,

Eric

$page=$_GET[‘page’];

Now $page is 1.(based on your URL)

echo preg_replace('~page=\\d+&?~', '', 'list_ungraded_review_questions_students.php?page=1&chapter_name=Quadratic_Fun ctions§ion_name=multiplying_binomials_by_geometry');

Something like that? :slight_smile:
