error_log与包含文件在同一目录中？ [英] error_log in the same directory as included files?

问题描述

我研究了不同的方法和指令，包括：

I've researched different methods and directives including:

• auto_prepend_file


• .user。 ini文件


• getcwd（）


• debug_backtrace（）

• auto_prepend_file
• .user.ini files
• getcwd()
• debug_backtrace()

我似乎无法找到一种方法来更改error_log的路径，以便在与包含/需要的文件相同的路径中登录。

And I can't seem to find a way to change the path of the error_log to log in the same path as the file being included/required.

For例如，说index.php有一行：

For example, say index.php has the line:

include('subdir/file.php');

如果 subdir / file.php 有一个语法错误，强制php创建 subdir / error_log ，而不是在与 index.php ，auto_prepend_file受到同样的限制，因为它在调用第一个脚本之前预先指定了文件，而不是包含每个文件。

If subdir/file.php has a syntax error, forcing php to create subdir/error_log, rather than the default behavior of creating error_log in the same path as index.php, auto_prepend_file suffers from this same limitation as it prepends the specified file before the first script called, rather than each file included.

我环顾四周，似乎无法找到合法的方法来做到这一点。通过这样做，我了解性能开销的影响，并计划仅将其用于开发目的。我相信这可以帮助隔离错误而不是使用堆栈跟踪，例如 debug_backtrace（），因为我可以使用终端脚本显示上次修改的最后错误日志，并查找有问题的文件比阅读大量错误日志要快得多。

I've looked around and can't seem to find a legitimate way to do this. I understand the implications of performance overhead by doing this, and plan to only use it for development purposes. I believe this can help isolate errors rather than using stack traces such as debug_backtrace(), as I can use a terminal script to show the last error logs by last modified, and find the offending files much quicker than reading through a massive error log.

我的目标是最终不要显示这些文件，显然是调试现有网站并且必须经历10GB错误日志或 tail / multitail 这可能有些麻烦。我正在尝试设计这种方法，以便可以通过路径隔离错误。有什么建议么？

My goal is ultimately not to have these files appear at all, obviously, as debugging already existing sites and having to go through a 10GB error logs or tail/multitailing it can be somewhat cumbersome. I'm trying to devise this method so errors can be isolated by path. Any suggestions?

推荐答案

根据hakre上面的建议，我创建了这个脚本，包含在任何php脚本的顶部：

Based on hakre's suggestions above, I've created this script, to be included at the top of any php script:

（如果你想分叉/下载它，这里也是我对这个文件的要点：在github上查看）

(also here is a gist I made of this file if you wish to fork/download it: view on github )

<?
function custom_error_debug($errno, $errstr, $errfile, $errline, $errvars) {
  $message = "";
  $message .= "[ " . date('Y-m-d h-i-s') . " ] Error: [$errno] $errstr on line $errline of $errfile ";

  //Dump all info to browser!
  //WARNING: Leave this commented except for extreme cases where you need to see all variables in use!
  //Using this will cause excessive processing time, and RAM. Use only as needed!
  /*if (!empty($errvars)) {
     echo $message . PHP_EOL . "Variables in use: <pre>";print_r($errvars); echo "</pre>";
     //WARNING: not ending execution here may cause the browser to overload on larger frameworks, comment out at your own risk!
     die();
  }*/

  //get the directory of the offending file, put a log in that path, and separate them by end of line, append to file
  file_put_contents ( dirname($errfile) . "/php_errors.log", $message . PHP_EOL, FILE_APPEND );

  //Dump all variables to file as well, (MAY CAUSE LARGE FILES, read above)
  //file_put_contents ( dirname($errfile) . "/php_errors.log", $errvars . PHP_EOL, FILE_APPEND );

  //Optionally end script execution
  //die();
}
set_error_handler('custom_error_debug');
?>
