UPDATE 2:
现在，我已从中删除以下内容.php文件:
<?php error_reporting( E_ALL ); ?>
我用php设置了显示错误.具体如下:
显示错误=On
错误报告设置为php.ini中的以下值:
ERROR_REPORTING=E_ALL|E_STRIGHT
重新启动Apache后，我仍然没有收到任何错误/警告.
UPDATE 1:个
我已将php.ini中的错误报告更改为:
错误报告=E_ALL&；
到
ERROR_REPORTING=E_ALL|E_STRIGHT
之后我重新启动了Apache，例如
/etc/init.d/apache2重启
但页面仍不会显示任何类型的错误/警告.
ORIGINAL QUESTION:
以下脚本正在生成警告，因为$err在if语句中.为什么这个警告没有显示在web浏览器的PHP页面上？
I have 到 look at the Apache logs 到 see the warning. Also, if I deliberately change the "insert in到" 到 "delete in到", it does not display an error on the PHP page. Why are the errors not displaying on the actual PHP page?
