I have an 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 the browser address bar.
