Working with the Query String Component

Getting The Query as an Array

If you're after the query of a url you may want to get it as an array. Don't worry, nothing easier than that:

$url = Url::parse('https://www.example.com/foo?bar=baz&key=value');
var_dump($url->queryArray());

Output

array(2) {
  ["bar"]=>
  string(3) "baz"
  ["key"]=>
  string(5) "value"
}

And the same method can be used to set the whole query string from an array:

$url = Url::parse('https://www.example.com/foo');
$url->queryArray(['param' => 'value', 'yo' => 'lo', 'crwlr' => 'url']);
var_dump($url->__toString());

Output

string(55) "https://www.example.com/foo?param=value&yo=lo&crwlr=url"

Advanced Query String API

If you're already on PHP 8 you can additionally install the crwlr / query-string package for a more advanced API to access and manipulate the query string.

composer require crwlr/query-string

After the package is installed the queryString() method returns an instance of the Query class from that package. You can find the docs for this class here. A quick example:

$url = Url::parse('https://www.example.com/listing?page[number]=3&page[size]=25');

$url->queryString()
    ->get('page')
    ->set('number', '4');

var_dump($url->__toString());

// string(68) "https://www.example.com/listing?page%5Bnumber%5D=4&page%5Bsize%5D=25"
