php解析url几种方式
- 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
- 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',
)
- 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',
)
- 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
- 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
