php 将数组转换网址URL参数

$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
$url = ‘http://username:[email protected]/path?arg=value#anchor‘;
print_r(parse_url($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
)
