Detailed explanation of php error handling encapsulation class

This article mainly introduces the error handling encapsulation class implemented by PHP, and analyzes PHP error judgment, prompts and log-related operation skills in the form of specific examples. Friends in need can refer to it. I hope it can help everyone.

1. Create the MyErrorHandler.php file

The code is as follows:

<?php
class MyErrorHandler {
  public $message;
  public $filename;
  public $line;
  public $vars = array();
  protected $_noticeLog = &#39;F:\root\noticeLog.log&#39;;
  public function __construct ($message,$filename,$line,$vars) {
    $this->message = $message;
    $this->filename = $filename;
    $this->line = $line;
    $this->vars = $vars;
  }
  public static function deal ($errno,$errmsg,$filename,$line,$vars) {
    $self = new self($errno,$errmsg,$filename,$line,$vars);
    switch ($errno) {
      case E_USER_ERROR:
        return $self->dealError();
        break;
      case E_USER_WARNING:
      case E_WARNING:
        return $self->dealWarning();
        break;
      case E_NOTICE:
      case E_USER_NOTICE:
        return $self->dealNotice();
      default:
        return false;
    }
  }
  /**
  * 致命的错误
  */
  public function dealError() {
    ob_start();
    debug_print_backtrace();
    $backtrace = ob_get_flush();
    $errorMsg = <<<EOF
出现了致命的错误，如下：
产生错误的文件：{$this->filename}
产生错误的信息：{$this->message}
产生错误的行号：{$this->line}
追踪信息{$backtrace}
EOF;
    error_log($errorMsg,1,&#39;279921301@qq.com&#39;,&#39;From:php[error错误日志]&#39;);
    exit(1);
  }
  /**
  * 警告的错误
  */
  public function dealWarning() {
    $errorMsg = <<<EOF
出现了警告的错误，如下：
产生警告的文件：{$this->filename}
产生警告的信息：{$this->message}
产生警告的行号：{$this->line}
EOF;
    return error_log($errorMsg,1,&#39;279921301@qq.com&#39;,&#39;From:php[error警告日志]&#39;);
  }
  /**
  * 通知的错误
  */
  public function dealNotice() {
    $datetime = date(&#39;Y-m-d H:i:s&#39;);
    $errorMsg = <<<EOF
出现了通知的错误，如下：
产生通知的文件：{$this->filename}
产生通知的信息：{$this->message}
产生通知的行号：{$this->line}
产生通知的时间：{$datetime}
EOF;
    return error_log($errorMsg,3,$this->_noticeLog);
  }
}

2. Test code

<?php
include "MyErrorHandler.php";
//报告所有 PHP 错误
error_reporting(-1);
//不显示错误信息
ini_set(&#39;display_errors&#39;,0);
set_error_handler(array(&#39;MyErrorHandler&#39;,&#39;deal&#39;));
echo $test; //Notice错误
settype($var,&#39;test&#39;); //警告错误
test();

Note: To send emails, you need to configure the mail function locally. You can refer to the previous article "How to configure sendmail in Windows and send emails through the mail() function in PHP".
