  **Voorbeeld: A  example**

```php
<?php
$url = 'http://username:password@hostname:9090/path?arg=value#anchor';

var_dump(parse_url($url));
var_dump(parse_url($url, PHP_URL_SCHEME));
var_dump(parse_url($url, PHP_URL_USER));
var_dump(parse_url($url, PHP_URL_PASS));
var_dump(parse_url($url, PHP_URL_HOST));
var_dump(parse_url($url, PHP_URL_PORT));
var_dump(parse_url($url, PHP_URL_PATH));
var_dump(parse_url($url, PHP_URL_QUERY));
var_dump(parse_url($url, PHP_URL_FRAGMENT));
?>
array(8) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(8) "hostname"
  ["port"]=>
  int(9090)
  ["user"]=>
  string(8) "username"
  ["pass"]=>
  string(8) "password"
  ["path"]=>
  string(5) "/path"
  ["query"]=>
  string(9) "arg=value"
  ["fragment"]=>
  string(6) "anchor"
}
string(4) "http"
string(8) "username"
string(8) "password"
string(8) "hostname"
int(9090)
string(5) "/path"
string(9) "arg=value"
string(6) "anchor"

Voorbeeld: A example with missing scheme

<?php
$url = '//www.example.com/path?googleguy=googley';

// Prior to 5.4.7 this would show the path as "//www.example.com/path"
var_dump(parse_url($url));
?>
array(3) {
  ["host"]=>
  string(15) "www.example.com"
  ["path"]=>
  string(5) "/path"
  ["query"]=>
  string(17) "googleguy=googley"
}

Opmerking: > This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the scheme where triple slashes () are allowed. For any other scheme this is invalid. file://``file:///...
