Parsing URL query in PHP

Question

Assuming a url of www.domain.org?x=1&y=2&z=3 , what would be a smart method to separate out the query elements of a url in php without using GET or REQUEST?

  $url = parse_url($url);
  echo $url[fragment];    

I don't think it's possible to return query parts separately is it? From what I can tell the query will just say x=1&y=2&z=3 but please let me know if I am wrong. Otherwise, what would you do to parse the $url[query] ?

Edit: Fragment should be Query instead. Sorry for the confusion, I am learning!

Answer 1

You can take the second step and parse the query string using parse_str .

$url = 'www.domain.org?x=1&y=2&z=3';
$url_parts = parse_url($url);
parse_str($url_parts['query'], $query_parts);
var_dump($query_parts);

I assumed you meant the query string instead of the fragment because there isn't a standard pattern for fragments.

Answer 2

parse_url function returns several components including query . To parse it you should run parse_str .

$parsedUrl = parse_url($url);
parse_str($parsedUrl['query'], $parsedQueryString);

If you are going just to parse your HTTP request URL:

• use $_REQUEST['x'] , $_REQUEST['y'] , $_REQUEST['z'] variables to access x,y,z parameters;

• use $_SERVER['QUERY_STRING'] to get whole URL querystring.

Answer 3

I was getting errors with some of the answers above but they did lead me to the right answer. Thanks guys.

 $url = 'www.domain.org?x=1&y=2&z=3';
 $query = $url[query]; 
 parse_str($query);
 echo "$x &y $z";

And this outputs: 1 2 3 , which is what I was trying to figure out.

Answer 4

As a one liner with no error checking

parse_str(parse_url($_SERVER['REQUEST_URI'], PHP_URL_QUERY), $query);

$query will contain the query string parameters
unlike PHP's $_GET , this will work with query params of any length

Answer 5

I highly recommend using this url wrapper https://github.com/weew/url (which I have written)

It is capable of parsing urls of complexity like protocol://username:password@subdomain.domain.tld:80/some/path?query=value#fragment and has many more goodies .
