Php 一个类文件适用于另一个类文件。它不能正常处理

php mysql

Php 一个类文件适用于另一个类文件。它不能正常处理,php,mysql,Php,Mysql,这里是config.php <?php define('DB_DSN','mysql:host=localhost;dbname=sales'); define('DB_USERNAME','root'); define('DB_PASSWORD',''); define("TBL_MEMBERS",'member'); define('TBL_PURCHASE','purchase'); define('TBL_SALES','sales'); ?> 提前感谢“未捕获异常”的

这里是config.php

<?php 
define('DB_DSN','mysql:host=localhost;dbname=sales');
define('DB_USERNAME','root');
define('DB_PASSWORD','');
define("TBL_MEMBERS",'member');
define('TBL_PURCHASE','purchase');
define('TBL_SALES','sales');

?>
提前感谢

“未捕获异常”的确切原因是什么？还有：http服务器错误日志文件显示了什么？这是错误[Sun Jan 03 12:15:52.564636 2016][：error][pid 4252][client:：1:60871]PHP致命错误：在/var/www/html/salesReport/company.class.PHP:71\n堆栈跟踪：\n#0/var/www/html/salesReport/purchase.PHP（57）：company->insert（）\n#1/var/www/html/salesReport/purchase.PHP（10）：companyProcessForm（）\n#2/var/www/html/salesReport/index.PHP（8）：包括（'/var/www/html/s…）\n#3{main}\n在第71行的/var/www/html/salesReport/company.class.php中抛出，referer：您可以看到这个类捕获了一个异常，然后依次抛出上面的异常。因此它基本上隐藏了捕获到的异常中给出的有价值的信息。为什么？相反，请查看捕获到的异常，它会告诉您出了什么问题！感谢您的回复。我是php新手，尝试一下。事实上，我的customer.class.php应该适用于sales_report。但是它随company.class.php提供。sales_report不会重定向，而是index.php。实际上我没有正确地理解它。
