私はphpが初めてで、mysql_queryからPDOに変更したばかりです。最初のページに製品を表示するために複数のクエリを実行する必要があり、テーブルには 150 万を超えるレコードがあります。
どうすればこれをもっと速くすることができますか？
作成したコードは次のとおりです。
#connection
$DBH = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
$DBH->setAttribute(PDO::ATTR_EMULATE_PREPARES, 0);
別ファイル
#fetch data
require_once('db_config.php');
$STH = $DBH->query("
