php通过getconfig读取配置文件的数组－明生-凯发官网入口
php后台管理中通常会设置一个config.php配置文件，将$config定义为一个数组变量，通过return 函数返回配置信息，以便集中且灵活管理各种配置信息。
(一）config.php定义一个简单数组
(一）config.php定义一个简单数组
return [
'app_id' => '1400009099',
'app_key' => '61f38*************7ec7b6',
'sms_sign' => '23**19',
'template_id' => '35**46',
];
getconfig.php：读取当前路径的config.php配置信息'app_id' => '1400009099',
'app_key' => '61f38*************7ec7b6',
'sms_sign' => '23**19',
'template_id' => '35**46',
];
$config = (require __dir__ . "/config.php");
$sender = new smssinglesender($config['app_id'],$config['app_key']);
（二）config.php定义一个二维数组$sender = new smssinglesender($config['app_id'],$config['app_key']);
return array(
'master'=>array(
'master_host'=>'1',
'master_name'=>'1',
'master_password'=>'1',
'master_port'=>'1',
'slave'=>array(
'slave_host'=>'2',
'slave_name'=>'2',
'slave_password'=>'2',
'slave_port'=>'2',
),
);
getconfig.php：读取当前路径的config.php配置信息'master'=>array(
'master_host'=>'1',
'master_name'=>'1',
'master_password'=>'1',
'master_port'=>'1',
'slave'=>array(
'slave_host'=>'2',
'slave_name'=>'2',
'slave_password'=>'2',
'slave_port'=>'2',
),
);
$config = require('config.php');
$config['db']['master']['host']= '';
$config['db']['master']['name']= '';
$config['db']['master']['password']= '';
$config['db']['master']['port']= '';
$config['db']['master']['slave']['host']= '';
$config['db']['master']['slave']['name']= '';
$config['db']['master']['slave']['password']= '';
这样就完成将config.php中的配置信息读入getconfig.php文件。
$config['db']['master']['host']= '';
$config['db']['master']['name']= '';
$config['db']['master']['password']= '';
$config['db']['master']['port']= '';
$config['db']['master']['slave']['host']= '';
$config['db']['master']['slave']['name']= '';
$config['db']['master']['slave']['password']= '';
