Question

I have a page that can have a link to in either one of the formats below:

• http://mydomain.com/linkID
• http://mydomain.com/linkID?9c1023a67eaf46cae864a31097

When the query part of the URL is present, I need to capture it with PHP. I tried using parse_url but I’m not really sure how to use it. Tried this

echo (parse_url($_SERVER['REQUEST_URI']['query'])); 

but it returns Array…

Answer 1

The optional 2nd parameter of parse_url allows you to specify precisely what portion of URL you need:

<?php
echo parse_url("http://mydomain.com/linkID", PHP_URL_QUERY); // <empty string>
echo parse_url("http://mydomain.com/linkID?9c1023a67eaf46cae864a31097", PHP_URL_QUERY); // 9c1023a67eaf46cae864a31097

On the other hand, it is easier to use a server variable, if applicable:

echo isset($_SERVER["QUERY_STRING"]) ? $_SERVER["QUERY_STRING"] : "";
