显示所有错误和警告 [英] Showing all errors and warnings
问题描述
更新2：
我现在已从.php文件中删除以下内容：
<？php error_reporting（E_ALL）; ？>
我已经在php.ini中设置了display_erros，如下所示：
display_errors = On
错误报告设置为以下php.ini
error_reporting = E_ALL | E_STRICT
重新启动apache后，我仍然没有收到错误/警告。
更新1：
我从php.ini更改了error_reporting：
error_reporting = E_ALL&
〜E_DEPRECATED
to
error_reporting = E_ALL | E_STRICT
之后我重新启动了apache，例如
/etc/init.d/apache2 restart
但该页面仍然不会显示任何类型的错误/警告。 / p>
ORIGINAL QUESTION：
以下脚本正在生成警告，因为$ err在if语句里面。为什么在网页浏览器的php页面上不显示此警告？我必须看看apache日志才能看到警告。此外，如果我将insert into更改为delete into，则不会在php页面上显示错误。为什么错误不显示在实际的PHP页面上？

显示错误可能会在 php.ini 或您的Apache配置文件。
您可以在脚本中打开它：
error_reporting（E_ALL）;
ini_set（'display_errors'，1）;
您应该在PHP错误日志中看到相同的消息。
UPDATE 2:
I have now removed the following from the .php file:
<?php error_reporting( E_ALL ); ?>
I have set display_erros in php.ini as follows:
display_errors = On
error reporting is set to the following in php.ini
error_reporting = E_ALL | E_STRICT
After restarting apache, I still get no errors/warnings.
UPDATE 1:
I have changed error_reporting in php.ini from:
error_reporting = E_ALL & ~E_DEPRECATED
to
error_reporting = E_ALL | E_STRICT
After which I restarted apache, e.g.
/etc/init.d/apache2 restart
But the page will still not display errors/warnings of any kind.
ORIGINAL QUESTION:
The following script is generating an warning because the $err being inside the if statement. Why is this warning not being displayed on the php page in a web browser? I have to look at apache logs to see the warning. Also, if I delibarately change the "insert into" to "delete into", it does not display an error on the php page. Why are the errors not displaying on the actual php page?

Display errors could be turned off in the php.ini or your Apache config file.
You can turn it on in the script:
error_reporting(E_ALL);
ini_set('display_errors', 1);
You should see the same messages in the PHP error log.
