举例子如下:

复制代码 代码如下:


$url = "http://www.electrictoolbox.com/php-extract-domain-from-full-url/";
$parts = parse_url($url);


输出:

复制代码 代码如下:


Array
(
[scheme] => http
[host] => www.electrictoolbox.com
[path] => /php-extract-domain-from-full-url/
)


又如:

复制代码 代码如下:


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


输出:

复制代码 代码如下:


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


可以看到,可以很容易分解出一个URL的各个部,那如果要拿指定的部分出来的话也很容易,如
echo parse_url($url, PHP_URL_PATH);
就是在第二个参数中,设定如下的参数:
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.
