PHP parse_url 一个好用的函数

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);

复制代码 代码如下:

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

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);
?>

复制代码 代码如下:

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