Using Purl

Creating Url instances is easy. You can specify the URL you want, or just use the current URL:

$url = new \Purl\Url('http://jwage.com');
$currentUrl = \Purl\Url::fromCurrent();

You can also create Url instances through the static parse method if you prefer that style:

$url = \Purl\Url::parse('http://jwage.com');

One benefit of using this method is you can chain methods together after creating the Url:

$url = \Purl\Url::parse('http://jwage.com')
    ->set('scheme', 'https')
    ->set('port', '443')
    ->set('user', 'jwage')
    ->set('pass', 'password')
    ->set('path', 'about/me')
    ->set('query', 'param1=value1&param2=value2')
    ->set('fragment', 'about/me?param1=value1&param2=value2');

echo $url->getUrl(); // https://jwage:password@jwage.com:443/about/me?param1=value1&param2=value2#about/me?param1=value1&param2=value2

// $url->path becomes instanceof Purl\Path
// $url->query becomes instanceof Purl\Query
// $url->fragment becomes instanceof Purl\Fragment

Path Manipulation

$url = new \Purl\Url('http://jwage.com');

// add path segments one at a time

// set the path data from a string
$url->path = 'about/me/another_segment'; // $url->path becomes instanceof Purl\Path

// get the path segments
print_r($url->path->getData()); // array('about', 'me', 'another_segment')

Query Manipulation

$url = new \Purl\Url('http://jwage.com');
$url->query->set('param1', 'value1');
$url->query->set('param2', 'value2');

echo $url->query; // param1=value1&param2=value2
echo $url; // http://jwage.com?param1=value1&param2=value2

// set the query data from an array
    'param1' => 'value1',
    'param2' => 'value2'

// set the query data from a string
$url->query = 'param1=value1&param2=value2'; // $url->query becomes instanceof Purl\Query
print_r($url->query->getData()); //array('param1' => 'value1', 'param2' => 'value2')

Fragment Manipulation

$url = new \Purl\Url('http://jwage.com');
$url->fragment = 'about/me?param1=value1&param2=value2'; // $url->fragment becomes instanceof Purl\Fragment

A Fragment is made of a path and a query and comes after the hashmark (#).

echo $url->fragment->path; // about/me
echo $url->fragment->query; // param1=value1&param2=value2
echo $url; // http://jwage.com#about/me?param1=value1&param2=value2

Domain Parts

Purl can parse a URL in to parts and its canonical form. It uses the list of domains from http://publicsuffix.org to break the domain into its public suffix, registerable domain, subdomain and canonical form.

$url = new \Purl\Url('http://about.jwage.com');

echo $url->publicSuffix; // com
echo $url->registerableDomain; // jwage.com
echo $url->subdomain; // about
echo $url->canonical; // com.jwage.about/

Staying Up To Date

The list of domains used to parse a URL into its component parts is updated from time to time. To ensure that you have the latest copy of the public suffix list, you can refresh the local copy of the list by running ./vendor/bin/pdp-psl data

Extract URLs

You can easily extract urls from a string of text using the extract method:

$string = 'some text http://google.com http://jwage.com';
$urls = \Purl\Url::extract($string);

echo $urls[0]; // http://google.com/
echo $urls[1]; // http://jwage.com/

Join URLs

You can easily join two URLs together using Purl:

$url = new \Purl\Url('http://jwage.com/about?param=value#fragment');
echo $url; // http://about.me/jwage?param=value#fragment

Or if you have another Url object already:

$url1 = new \Purl\Url('http://jwage.com/about?param=value#fragment');
$url2 = new \Purl\Url('http://about.me/jwage');
echo $url1; // http://about.me/jwage?param=value#fragment
