What are the reasons why PHP would echo errors, even with error_reporting(0)?
提问by Valdemarick
What are some reasons why PHP would force errors to show, no matter what you tell it to disable?
无论您告诉它禁用什么，PHP 都会强制显示错误的一些原因是什么？
I have tried
我试过了
error_reporting(0);
ini_set('display_errors', 0);
with no luck.
没有运气。

Note the caveat in the manual at http://uk.php.net/error_reporting:
请注意http://uk.php.net/error_reporting手册中的警告：
Most of E_STRICT errors are evaluated at the compile time thus such errors are not reported in the file where error_reporting is enhanced to include E_STRICT errors (and vice versa).
大多数 E_STRICT 错误是在编译时评估的，因此在 error_reporting 增强以包含 E_STRICT 错误的文件中不会报告此类错误（反之亦然）。
If your underlying system is configured to report E_STRICT errors, these may be output before your code is even considered. Don't forget, error_reporting/ini_set are runtime evaluations, and anything performed in a "before-run" phase will not see their effects.
如果您的底层系统被配置为报告 E_STRICT 错误，这些可能在您的代码被考虑之前就被输出。不要忘记，error_reporting/ini_set 是运行时评估，在“运行前”阶段执行的任何操作都不会看到它们的影响。
Based on your comment that your error is...
根据您的评论，您的错误是...
Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /usr/home/REDACTED/public_html/dev.php on line 11
解析错误：语法错误，意外的 T_VARIABLE，需要 ',' 或 ';' 在第 11 行的 /usr/home/REDACTED/public_html/dev.php
Then the same general concept applies. Your code is never run, as it is syntactically invalid (you forgot a ';'). Therefore, your change of error reporting is never encountered.
然后应用相同的一般概念。您的代码永远不会运行，因为它在语法上无效（您忘记了“;”）。因此，永远不会遇到您更改错误报告的情况。
Fixing this requires a change of the system level error reporting. For example, on Apache you may be able to place...
解决此问题需要更改系统级错误报告。例如，在 Apache 上，您可以将...
php_value error_reporting 0
php_value error_reporting 0
in a .htaccess file to suppress them all, but this is system configuration dependent.
在 .htaccess 文件中将它们全部取消，但这取决于系统配置。
Pragmatically, don't write files with syntax errors :)
务实地，不要写有语法错误的文件:)

To prevent errors from displaying you can
为了防止显示错误，您可以
- Write in a .htaccess: php_flag display_errors 0
- Split your code in separate modules where the main (parent) PHP file only sets the error_logging and then include() the other files.
- 写入 .htaccess: php_flag display_errors 0
- 在单独的模块中拆分您的代码，其中主（父）PHP 文件仅设置 error_logging，然后 include() 其他文件。

Is set_error_handler()used anywhere in your script? This overrides error_reporting(0).
是否set_error_handler()在脚本中的任何地方使用？这将覆盖error_reporting(0).

To ensure there's no syntax errors in your file, run the following:
为确保您的文件中没有语法错误，请运行以下命令：
php -l YOUR_FILE_HERE.php
This will output something like this:
这将输出如下内容：
PHP Parse error: syntax error, unexpected '}' in Connection.class.php on line 31

If the setting is specified in Apache using php_admin_value, it can't be changed in .htaccess or at runtime.
如果使用php_admin_value在 Apache 中指定设置，则无法在 .htaccess 或运行时更改。

Use log_errorsfor them to be logged instead of displayed.
使用log_errors来记录而不是显示它们。
