调整CodeIgniter错误报告级别

修改位置：CI根目录 index.php

为开发环境与生产环境定义错误报告级别

 1 if (defined(‘ENVIRONMENT‘))
 2 {
 3     switch (ENVIRONMENT)
 4     {
 5         case ‘development‘:
 6             error_reporting(E_ALL);
 7         break;
 8
 9         case ‘testing‘:
10         case ‘production‘:
11             error_reporting(E_ERROR);
12         break;
13
14         default:
15             exit(‘The application environment is not set correctly.‘);
16     }
17 }
