How to get parameters from a URL string?

I have a HTML form field

$_POST["url"]
having some URL strings as the value.
Example values are:


https://example.com/test/1234?email=xyz@test.com
https://example.com/test/1234?basic=2&email=xyz2@test.com
https://example.com/test/1234?email=xyz3@test.com
https://example.com/test/1234?email=xyz4@test.com&testin=123
https://example.com/test/the-page-here/1234?someurl=key&email=xyz5@test.com


etc.

How can I get only the
email
parameter from these URLs/values?

Please note that I am not getting these strings from browser address bar.

Answer

You can use the parse_url() and parse_str() for that.

$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['email'];

If you want to get the $url dynamically with PHP, take a look at this question:
