数据库连接“Mysql”丢失，或无法创建。在Cake PHP中 [英] Database connection "Mysql" is missing, or could not be created. in Cake PHP

问题描述

Cake is NOT able to connect to the database.

Database connection "Mysql" is missing, or could not be created.
SQLSTATE[42000] [1044] Access denied for user ''@'localhost' to database 'database_name'

以上是我在Windows 7中使用Cake php和Mysql（在XAMPP中）时出现的错误信息



但是我使用简单的代码

Above is the error message rise when i use Cake php and Mysql (in XAMPP)in windows 7

but i use simple code

<?php
// Create connection
$con=mysqli_connect("localhost","root","","database_name");

// Check connection
if (mysqli_connect_errno($con))
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
 else
  {
   echo "connected to MySQL " ;
  } 
?> 

[^]但这段代码运行正常。 。

}
其他

echo 连接到MySQL;
}
