PHP的解析错误将不会显示 [英] php parse errors won't show

问题描述

我正在运行ubuntu 10.04 + nginx + php-fpm 5.4

I'm running ubuntu 10.04 + nginx + php-fpm 5.4

如果我在php.ini中设置了display_errors = On，则会显示所有错误.如果相反，我将其设置为关闭，然后使用ini_set('display_errors，'1');它们也会直接在脚本中显示，但不会显示解析错误，只是空白页.我也尝试过error_reporting和E_STRICT，但我找不到办法！

If I set display_errors = On in php.ini all errors are printed. If Instead I set that to off and then use ini_set('display_errors, '1'); directly in the script they will show as well but not the parse errors, just a blank page. I tried to play with error_reporting too and E_STRICT but I couldn't find a way!

推荐答案

如果在php.ini中禁用display_errors，随后又使用ini_set()在PHP脚本中启用它，则只有在包含该ini_set()调用的行已执行.

If you disable display_errors in php.ini, and later enable it in your PHP script using ini_set(), it will only be enabled after the line containing that ini_set() call has been executed.

解析错误发生在 PHP脚本启动之前 –解析PHP文件时(因此称为解析错误"名称).

Parse errors occur before the PHP script even starts -- when the PHP file is parsed (hence the "parse error" name).

这意味着它们在您的ini_set()甚至没有被执行的机会之前就发生了-这意味着，在您的情况下，当解析错误发生时，display_errors没有启用；结果，您什么也不会显示.

Which means they occur before your ini_set() has even a chance of being executed -- which means that, in your case, display_errors is not enabled when the parse error occurs ; and, as a consequence, you don't get anything displayed.
