Introduction to parse_url () function usage in php

A useful function in PHP, parse_url, is particularly convenient for information capture analysis. For example:

The code is as follows:	Copy code
$ Url = "http://www.111cn.net/aaaa/"; $ parts = parse_url ($ url ); Output: Array ( [Scheme] => http [Host] => www.111cn.net [Path] =>/aaaa/ )

Another example:

The code is as follows:	Copy code
<? 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, it is easy to 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 parameters:
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.
