這個是包含連接數(shù)據(jù)庫的PHP文件，可以這樣寫
<?php
define('DB_HOST','localhost');
define('DB_USER','root');
define('DB_PSW','連接密碼');
define('DB_NAME','數(shù)據(jù)庫名稱');
define('DB_CHARSET','utf-8');
$cnn=mysqli_connect(DB_HOST,DB_USER,DB_PSW,DB_NAME);
/*if (!$cnn){
? ?die("連接數(shù)據(jù)庫失敗").mysqli_error($cnn);
}
echo "連接數(shù)據(jù)庫成功";*/
?>
