How do I log errors and warnings into a file?
提问by Gorep
How do I turn on all error and warnings and log them to a file, but to set up all of that within the script (not changing anything in php.ini)?
如何打开所有错误和警告并将它们记录到文件中，但要在脚本中设置所有这些（不更改 php.ini 中的任何内容）？
I want to define a file name and so that all errors and warnings get logged into it.
我想定义一个文件名，以便将所有错误和警告记录到其中。

Use the following code:
使用以下代码：
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
error_log( "Hello, errors!" );
Then watch the file:
然后看文件：
tail -f /tmp/php-error.log
Or update php.inias described in this blog entryfrom 2008.
或者php.ini按照2008 年这篇博客文章中的描述进行更新。

See
看
error_log— Send an error message somewhere
error_log— 在某处发送错误消息
Example
例子
error_log("You messed up!", 3, "/var/tmp/my-errors.log");
You can customize error handling with your own error handlersto call this function for you whenever an error or warning or whatever you need to log occurs. For additional information, please refer to the Chapter Error Handling in the PHP Manual
您可以使用自己的错误处理程序自定义错误处理，以便在发生错误或警告或需要记录的任何内容时为您调用此函数。更多信息请参考PHP手册中的错误处理章节

Simply put these codes at top of your PHP/index file:
只需将这些代码放在 PHP/index 文件的顶部：
error_reporting(E_ALL); // Error/Exception engine, always use E_ALL
ini_set('ignore_repeated_errors', TRUE); // always use TRUE
ini_set('display_errors', FALSE); // Error/Exception display, use FALSE only in production environment or real server. Use TRUE in development environment
ini_set('log_errors', TRUE); // Error/Exception file logging engine.
ini_set('error_log', 'your/path/to/errors.log'); // Logging file path

add this code in .htaccess(as an alternative of php.ini/ ini_setfunction):
在.htaccess 中添加此代码（作为php.ini/ ini_set函数的替代）：
<IfModule mod_php5.c>
php_flag log_errors on
php_value error_log ./path_to_MY_PHP_ERRORS.log
# php_flag display_errors on
</IfModule>
* as commented: this is for Apache-type servers, and not for Nginxor others.
* 评论：这是针对Apache类型的服务器，而不是针对Nginx或其他服务器。

Take a look at the log_errorsconfiguration option in php.ini. It seems to do just what you want to. I think you can use the error_logoption to set your own logging file too.
查看log_errorsphp.ini中的配置选项。它似乎只是做你想做的。我认为您也可以使用该error_log选项来设置自己的日志文件。
When the log_errorsdirective is set to On, any errors reported by PHP would be logged to the server log or the file specified with error_log. You can set these options with ini_settoo, if you need to.
当该log_errors指令设置为 时On，PHP 报告的任何错误都将记录到服务器日志或用 指定的文件中error_log。ini_set如果需要，您也可以设置这些选项。
(Please note that display_errorsshould be disabled in php.ini if this option is enabled)
（请注意，display_errors如果启用此选项，则应在 php.ini 中禁用该选项）

In addition, you need the "AllowOverride Options" directive for this to work. (Apache 2.2.15)
此外，您需要“AllowOverride Options”指令才能使其工作。（阿帕奇 2.2.15）
