php解析url的几种方式
1、利用$_SERVER内置数组变量
访问:http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1
//URL的参数
echo $_SERVER['QUERY_STRING'];
返回:
m=admin&c=index&a=lists&catid=1&page=1
//包含文件名
echo $_SERVER["REQUEST_URI"];
返回:
/test.php?m=admin&c=index&a=lists&catid=1&page=1
2、利用pathinfo内置函数
- echo "<pre>";
- $url = 'http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1#top';
- var_export(pathinfo($url));
返回:
- array (
- 'dirname' => 'http://localhost',
- 'basename' => 'test.php?m=admin&c=index&a=lists&catid=1&page=1#top',
- 'extension' => 'php?m=admin&c=index&a=lists&catid=1&page=1#top',
- 'filename' => 'test',
- )
3、利用parse_url内置函数
- echo "<pre>";
- $url = 'http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1#top';
- var_export(parse_url($url));
返回:
- array (
- 'scheme' => 'http',
- 'host' => 'localhost',
- 'path' => '/test.php',
- 'query' => 'm=admin&c=index&a=lists&catid=1&page=1',
- 'fragment' => 'top',
- )
4、利用basename内置函数
- echo "<pre>";
- $url = 'http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1#top';
- var_export(basename($url));
返回:
test.php?m=admin&c=index&a=lists&catid=1&page=1#top
5、正则匹配
- echo "<pre>";
- $url = 'http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1#top';
- preg_match_all("/(\w+=\w+)(#\w+)?/i",$url,$match);
- var_export($match);
返回:
- array (
- 0 =>
- array (
- 0 => 'm=admin',
- 1 => 'c=index',
- 2 => 'a=lists',
- 3 => 'catid=1',
- 4 => 'page=1#top',
- ),
- 1 =>
- array (
- 0 => 'm=admin',
- 1 => 'c=index',
- 2 => 'a=lists',
- 3 => 'catid=1',
- 4 => 'page=1',
- ),
- 2 =>
- array (
- 0 => '',
- 1 => '',
- 2 => '',
- 3 => '',
- 4 => '#top',
- ),
- )
url常用处理方法
- /**
- * 将字符串参数变为数组
- * @param $query
- * @return array
- */
- function convertUrlQuery($query)
- {
- $queryParts = explode('&', $query);
- $params = array();
- foreach ($queryParts as $param) {
- $item = explode('=', $param);
- $params[$item[0]] = $item[1];
- }
- return $params;
- }
- /**
- * 将参数变为字符串
- * @param $array_query
- * @return string
- */
- function getUrlQuery($array_query)
- {
- $tmp = array();
- foreach ($array_query as $k => $param) {
- $tmp[] = $k . '=' . $param;
- }
- $params = implode('&', $tmp);
- return $params;
- }
例:
- echo "<pre>";
- $url = 'http://localhost/test.php?m=admin&c=index&a=lists&catid=1&page=1#top';
- $arr = parse_url($url);
- $arr_query = convertUrlQuery($arr['query']);
- var_export($arr_query);
返回:
- array (
- 'm' => 'admin',
- 'c' => 'index',
- 'a' => 'lists',
- 'catid' => '1',
- 'page' => '1',
- )
- var_export(getUrlQuery($arr_query));
返回:
m=admin&c=index&a=lists&catid=1&page=1
