php有哪些解析url的方法?相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。

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
