Enabling error display in PHP via htaccess only
提问by Ogugua Belonwu
I am testing a website online.
我正在在线测试一个网站。
Right now, the errors are not being displayed (but I know they exist).
现在，没有显示错误（但我知道它们存在）。
I have access to only the .htaccessfile.
我只能访问该.htaccess文件。
How do I make all errors to display using my .htaccessfile?
如何使用我的.htaccess文件显示所有错误？
I added these lines to my .htaccessfile:
我将这些行添加到我的.htaccess文件中：
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
And the pages nowdisplay:
现在页面显示：
Internal server error
内部服务器错误

php_flag display_errors on
To turn the actual display of errors on.
打开错误的实际显示。
To set the types of errors you are displaying, you will need to use:
要设置您显示的错误类型，您需要使用：
php_value error_reporting <integer>
Combined with the integer values from this page: http://php.net/manual/en/errorfunc.constants.php
结合本页的整数值：http: //php.net/manual/en/errorfunc.constants.php
Note if you use -1 for your integer, it will show all errors, and be future proof when they add in new types of errors.
请注意，如果您对整数使用 -1，它将显示所有错误，并在他们添加新类型的错误时成为未来证明。

I feel like adding more details to the existing answer:
我想在现有答案中添加更多细节：
# PHP error handling for development servers
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on
php_flag track_errors on
php_value docref_root 0
php_value docref_ext 0
php_value error_log /full/path/to/file/php_errors.log
php_value error_reporting -1
php_value log_errors_max_len 0
Give 777 or 755 permission to the log file and then add the code
给日志文件777或755权限，然后添加代码
<Files php_errors.log>
Order allow,deny
Deny from all
Satisfy All
</Files>
at the end of .htaccess. This will protect your log file.
在 .htaccess 的末尾。这将保护您的日志文件。
These options are suited for a development server. For a production server you should not display any error to the end user. So change the display flags to off.
这些选项适用于开发服务器。对于生产服务器，您不应向最终用户显示任何错误。因此，将显示标志更改为off。
