部屋IDをチェックするforループがあるphpゲームで使用される関数があります。基本的に、for ループは 2 回実行する必要があるときに 1 回だけ実行されます。以下のコード ブロックは、($i を使用した最初の for ループ) を示しています。

// successful sql login & $player is correctly set with '', and all below sql
// statements execute correctly. $count is 2
function setMonstersLocation($player,$rooms_id){
if (mysql_result(mysql_query("SELECT state FROM present WHERE player = $player AND items_id IS NULL AND monsters_id IS NULL AND quantity IS NULL AND rooms_id IS NOT NULL"),0) == 0){

                    for ($l = 0; $l < $count; $l+=1){

                    }

            else { $sql = mysql_query("UPDATE present SET rooms_id=-1 WHERE player = $player AND items_id IS NULL AND monsters_id=$result");}
        }
    }
    $sql = mysql_query("UPDATE present SET state = 1 WHERE player = $player AND items_id IS NULL AND monsters_id IS NULL AND quantity IS NULL AND rooms_id IS NOT NULL");
} else {
    $sql = mysql_query("UPDATE present SET state = 0 WHERE player = $player AND items_id IS NULL AND monsters_id IS NULL AND quantity IS NULL AND rooms_id IS NOT NULL");
}

}

$count が 2 の場合、for ループは 1 回だけ実行されます。for ループが実行されるたびに mysql テーブルの値に 1 を追加して、これを確認しました。値は 1 回だけ増加します。

上部の if ステートメントは、1 ティックおきに関数を実行することです。

$countforループの条件部分は、ループの反復ごとに評価されるため、メインループ内の値を変更することはできません。変数名をもっと意味のあるものに変更する必要があります。

これを試して：

// statements execute correctly. $count is 2

    // number of players.
    $playerCount = mysql_result($sql,0);
    $sql = mysql_query("SELECT monsters_id FROM present WHERE player = $player AND items_id IS NULL AND monsters_id > 100 AND monsters_id < 300 ORDER BY monsters_id");
