一、javascript：

1. 代码：

   /*
   @desc：url解析函数
   @author <lee> [<complet@163.com>]
   @param url 要查询的url
   @return ret 解析后的对象
   */
   function parseurl(url){
   var reg = /(?:([A-Za-z]+):)?(\/{0,3})?(?:(.*):(.*)@)?([0-9.\-A-Za-z]+)(?::(\d+))?(?:\/([^?#]*))?(?:\?([^#]*))?(?:#(.*))?/
   var res = reg.exec(url)
   var scheme = (res[1])?res[1]:'http'
   var user = (res[3])?res[3]:''
   var pass = (res[4])?res[4]:''
   var host = (res[5])?res[5]:''
   var port = (res[6])?res[6]:''
   var path = (res[7])?res[7]:''
   var query = (res[8])?res[8]:''
   var fragment = (res[9])?res[9]:''
   var ret = {
       scheme:scheme,
       user:user,
       pass:pass,
       host:host,
       port:port,
       path:path,
       query:query,
       fragment:fragment
   }
   return ret
   }

2. 测试：

   var url = "https://user:pass@www.baidu.com:80/a/b/?name=lee&sex=male#id";
   var ret = parseurl(url)
   console.log(ret)

3. 输出：

   { scheme: 'https',
   user: 'user',
   pass: 'pass',
   host: 'www.baidu.com',
   port: '80',
   path: 'a/b/',
   query: 'name=lee&sex=male',
   fragment: 'id' }

   二、php：

4. 代码（自带）：

   parse_url()

5. 测试：

   <?php
   $url = "http://user:pass@www.baidu.com:80/a/b?name=lee&sex=male#id";
   $ret = parse_url($url);
   var_dump($ret);

6. 输出：

   array(8) {
   ["scheme"]=>
   string(4) "http"
   ["host"]=>
   string(13) "www.baidu.com"
   ["port"]=>
   int(80)
   ["user"]=>
   string(4) "user"
   ["pass"]=>
   string(4) "pass"
   ["path"]=>
   string(4) "/a/b"
   ["query"]=>
   string(17) "name=lee&sex=male"
   ["fragment"]=>
   string(2) "id"
   }
