PHP解析URL并得到URL中的参数

/**
* 获取url中的参数
*/
 
function getUrlParams($url){
 
$arr = parse_url($url);
$query = $arr['query'];
$queryParts = explode('&', $query);
 
$params = array();
foreach ($queryParts as $param)
{
$item = explode('=', $param);
$params[$item[0]] = $item[1];
}
 
return $params;
}
 
 
//使用示例
 
$url = 'http://test.com/index.php?id=123&type=1';
 
$urlParams = getUrlParams($url);
$data['id'] = $urlParams['id'];
 
$data['type'] = $urlParams['type'];

<?php
//例举一个URL格式的字符串:
$str = 'http://test.com/testdir/index.php?param1=10&param2=20&param3=30&param4=40&param5=50&param6=60';
 
//1.0 用parse_url解析URL,此处是$str
$arr = parse_url($str);
var_dump($arr);
 
 
//2.0 将URL中的参数取出来放到数组里
$arr_query = convertUrlQuery($arr['query']);
var_dump($arr_query);
 
 
//3.0 将 参数数组 再变回 字符串形式的参数格式
var_dump(getUrlQuery($arr_query));
 
 
/**
 * Returns the url query as associative array
 *
 * @param    string    query
 * @return    array    params
 */
function convertUrlQuery($query)
{
    $queryParts = explode('&', $query);
     
    $params = array();
    foreach ($queryParts as $param)
    {
        $item = explode('=', $param);
        $params[$item[0]] = $item[1];
    }
     
    return $params;
}
 
function getUrlQuery($array_query)
{
    $tmp = array();
    foreach($array_query as $k=>$param)
    {
        $tmp[] = $k.'='.$param;
    }
    $params = implode('&',$tmp);
    return $params;
}
