PHP URL 与数组的转化

$array =array ( ‘id‘ =123, ‘name‘ = ‘dopost‘ );
echo http_build_query( $array );
//得到结果
id=123name=dopost

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:

<?php 
$url = ‘http://username:password@hostname/path?arg=value#anchor‘; 
print_r(parse_url($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 
)
