下面附上我的PHP代码。表mylibrary
包含 isbn 和 title 记录。PHP 脚本无法连接到 mysql。为什么 ?
<?php
$conn_error = 'Could not connect.';
$mysql_host = 'localhost';
$mysql_user = 'root';
$mysql_pass = '';
$mysql_db='b_database';
if(!@mysql_connect($mysql_host, $mysql_user,$mysql_pass)|| !@mysql_select_db($mysql_db)){
die($conn_error);
}
?>
