为什么即使有error_reporting(0)，PHP也会回显错误的原因是什么? [英] What are the reasons why PHP would echo errors, even with error_reporting(0)?

问题描述

无论您叫它禁用什么，PHP都会强制显示错误的原因有哪些?

What are some reasons why PHP would force errors to show, no matter what you tell it to disable?

我尝试过

error_reporting(0);
ini_set('display_errors', 0); 

没有运气.

推荐答案

请注意手册中的注意事项，网址为 http://uk.php.net/error_reporting :

Note the caveat in the manual at http://uk.php.net/error_reporting:

大多数E_STRICT错误是在编译时评估的，因此在将error_reporting增强为包括E_STRICT错误的文件中不会报告此类错误(反之亦然).

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).

如果您的基础系统配置为报告E_STRICT错误，则可能在考虑代码之前就输出了这些错误.别忘了，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.

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.

根据您的评论，您的错误是...

Based on your comment that your error is...

解析错误:语法错误，意外的T_VARIABLE，期望为'，'或';'在第11行的/usr/home/REDACTED/public_html/dev.php中

Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /usr/home/REDACTED/public_html/dev.php on line 11

然后应用相同的一般概念.您的代码从不运行，因为它在语法上是无效的(您忘记了;").因此，永远不会遇到您的错误报告更改.

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.

要解决此问题，需要更改系统级错误报告.例如，在Apache上，您可以放置​​...

Fixing this requires a change of the system level error reporting. For example, on Apache you may be able to place...

php_value错误报告0

php_value error_reporting 0

.htaccess文件中的所有内容可将其全部删除，但这取决于系统配置.

in a .htaccess file to suppress them all, but this is system configuration dependent.

实用上，请勿写入语法错误的文件:)

Pragmatically, don't write files with syntax errors :)
