如何使用PHP将浏览器输出写入日志文件？ [英] How to write browser output to log file using PHP?

问题描述

我的脚本是由Cron作业运行的。所以，当它运行时，我看不出任务的输出是什么。 （错误等等。）

所以我需要使用PHP将浏览器输出写入日志文件。我该怎么做？

I have the script is which runned by Cron jobs. So, while it runs, I can't see what output of the task is. (errors and so on.)
So I need to write browser output to log file using PHP. How can I do this ?

推荐答案

我将此脚本用于错误日志：

I use this script for error logs:

// Destinations
define("ADMIN_EMAIL", "[e-mail]");
define("LOG_FILE", "/my/home/errors.log");

// Destination types
define("DEST_EMAIL", "1");
define("DEST_LOGFILE", "3");

/**
  * my_error_handler($errno, $errstr, $errfile, $errline)
  *
  * Author(s): thanosb, ddonahue
  * Date: May 11, 2008
  * 
  * custom error handler
  *
  * Parameters:
  *  $errno:   Error level
  *  $errstr:  Error message
  *  $errfile: File in which the error was raised
  *  $errline: Line at which the error occurred
  */

function my_error_handler($errno, $errstr, $errfile, $errline)
{  
  switch ($errno) {
    case E_USER_ERROR:
      // Send an e-mail to the administrator
      error_log("Error: $errstr \n Fatal error on line $errline in file $errfile \n", DEST_EMAIL, ADMIN_EMAIL);

      // Write the error to our log file
      error_log("Error: $errstr \n Fatal error on line $errline in file $errfile \n", DEST_LOGFILE, LOG_FILE);
      break;

    case E_USER_WARNING:
      // Write the error to our log file
      error_log("Warning: $errstr \n in $errfile on line $errline \n", DEST_LOGFILE, LOG_FILE);
      break;

    case E_USER_NOTICE:
      // Write the error to our log file
      error_log("Notice: $errstr \n in $errfile on line $errline \n", DEST_LOGFILE, LOG_FILE);
      break;

    default:
      // Write the error to our log file
      error_log("Unknown error [#$errno]: $errstr \n in $errfile on line $errline \n", DEST_LOGFILE, LOG_FILE);
      break;
  }

  // Don't execute PHP's internal error handler
  return TRUE;
}


// Use set_error_handler() to tell PHP to use our method
$old_error_handler = set_error_handler("my_error_handler");

它可以完全控制引发错误时要采取的操作。
