Use the PHP function parse_url to analyze information capture

1. $ Url = "http://www.electrictoolbox.
   Com/php-extract-domain-from-full-url /";
2. $ Parts = parse_url ($ url );

Output:

1. Array
2. (
3. [Scheme] =>Http
4. [Host] =>Www.electrictoolbox.com
5. [Path] =>/Php-extract-
   Domain-from-full-url/
6. )

Another example is how to use the PHP function parse_url:

 
 

  
  
< ?php  
  
  
$url = 'http://username:password
@hostname/path?arg=value#anchor';  
  
  
print_r(parse_url($url));  
  
  
echo parse_url($url, PHP_URL_PATH);  
  
  
?> 
 
 

Output:

 
 

  
  
Array  
  
  
(  
  
  
[scheme] => http  
  
  
[host] => hostname  
  
  
[user] => username  
  
  
[pass] => password  
  
  
[path] => /path  
  
  
[query] => arg=value 
  
  
[fragment] => anchor  
  
  
)  
 
 

As you can see, the PHP function parse_url can easily break down all parts of a URL. It is also easy to take the specified part, as shown in figure

Echo parse_url ($ url, PHP_URL_PATH); in the second parameter, set the following parameter:

PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT.
