PHP는 URL을 구문 분석하여 URL의 매개변수 값을 가져옵니다.

$url = 'http://www.baidu.com/index.php?
m=content&c=index&a=lists&catid=6&area=0&author=0&h=0®ion=0&s=1&page=1';
parse_str(parse_url($url)[query],$query_arr);
var_dump($query_arr);

array (size=10)
          'm' => string 'content' (length=7)
          'c' => string 'index' (length=5)
          'a' => string 'lists' (length=5)
          'catid' => string '6' (length=1)
          'area' => string '0' (length=1)
          'author' => string '0' (length=1)
          'h' => string '0' (length=1)
          'region' => string '0' (length=1)
          's' => string '1' (length=1)
          'page' => string '1' (length=1)
