PHP parses the URL and gets the parameters in the URL

!--? php// Example of a URL-formatted string: $STR = ' HTTP://TEST.COM/TESTDIR/INDEX.PHP?PARAM1=10&PARAM2=20&PARAM3=30&PARAM4=40&PARAM5=50&PARAM6 =60 ';//1 uses Parse_url to parse the URL, here is $str$arr = Parse_url ($STR); Var_dump ($arr);//2 takes a parameter out of the URL and puts it in the array $arr_query =    Converturlquery ($arr [' query ']); Var_dump ($arr _query);//3 the parameter array back to the parameter format in string form Var_dump (Geturlquery ($arr _query));/** * Returns the URL query as associative array * @param string query * @return Array params */fun    Ction Converturlquery ($query) {$queryParts = explode (' & ', $query);    $params = Array ();        foreach ($queryParts as $param) {$item = explode (' = ', $param);    $params [$item [0]] = $item [1]; } return $params;}    function Geturlquery ($array _query) {$tmp = array ();    foreach ($array _query as $k =--> $param) {$tmp [] = $k. ' = '. $param;    } $params = Implode (' & ', $tmp); return $params;}?
