我有一個(gè) php 腳本從 mysql 數(shù)據(jù)庫執(zhí)行搜索記錄，如何添加從 mysql 查詢返回的總計(jì)數(shù)？例如。我搜索“ABC”，總搜索結(jié)果為 3，我想在搜索“找到的總搜索數(shù)：3”后顯示此結(jié)果。到目前為止一直在嘗試下面的代碼，但沒有取得任何好的進(jìn)展，任何人都可以提供幫助嗎？謝謝<?phpdefine('DB_HOST', 'localhost');define('DB_NAME', 'stock');define('DB_CHARSET', 'utf8mb4');define('DB_USER', 'root');define('DB_PASSWORD', '');try{    $pdo = new PDO("mysql:host=" .
