我的问题是我在 MySqlConnector.php 中收到以下错误。
Undefined variable: host error
我使用两个不同的连接进行读/写。我根据系统使用的环境将它们合并到 config/database.php 文件中。这是mysql连接代码。
<?php
switch($_SERVER['LARAVEL_ENV']){
case 'production':
$connections = array(
'mysql' => array(
'read' => array(
'host' => '127.0.0.1',
),
'write' => array(
'host' => 'hosturl',
),
'driver' => 'mysql',
'database' => 'app_system',
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
'mysql2' => array(
'read' => array(
'host' => '127.0.0.1',
),
'write' => array(
'host' => 'hosturl',
),
'driver' => 'mysql',
'database' => 'app_userdata',
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
);
break;
case 'beta':
$connections = array(
'mysql' => array(
'read' => array(
'host' => '127.0.0.1',
),
'write' => array(
'host' => 'hosturl',
),
'driver' => 'mysql',
'database' => 'app_system',
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
'mysql2' => array(
'read' => array(
'host' => '127.0.0.1',
),
'write' => array(
'host' => 'hosturl',
),
'driver' => 'mysql',
'database' => 'app_userdata',
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
);
break;
case 'development':
$connections = array(
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'app_system',
'username' => 'root',
'password' => 'root',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
'mysql2' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'app_userdata',
'username' => 'root',
'password' => 'root',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
);
break;
}
return array(
'fetch' => PDO::FETCH_CLASS,
'default' => 'mysql',
'connections' => $connections,
'migrations' => 'migrations',
'redis' => array(
'cluster' => true,
'default' => array(
'host' => '127.0.0.1',
'port' => 6379,
'database' => 0,
),
),
);
我想做的就是使用不同的主机进行读取和使用另一个主机进行写入。当我在 localhost 中使用一个连接时,我没有收到任何错误。但是在多个连接中,我得到了错误。错误原因是什么?
最佳答案
好的,我发现了问题。这是因为laravel版本。我将 laravel 4.0 更新到 4.1,问题解决了。
