php自定义错误处理用法实例

本文实例讲述了php自定义错误处理用法。分享给大家供大家参考。具体如下：

    <?php
    error_reporting(E_ALL);
    function ErrHandler($errorno, $errorstr, $errorfile, $errorline)
    {
      $display = true;
      $notify = false;
      $halt_script = false;
      $error_msg = "<br>The $errorno error is occurring at $errorline in
      $errorfile<br>";
      switch($errorno)
      {
       case E_USER_NOTICE:
       case E_NOTICE:
       $halt_script = false;
       $notify = true;
       $label = "<B>Notice</B>";
       break;
       case E_USER_WARNING:
       case E_WARNING:
       $halt_script = false;
       $notify = true;
       $label = "<b>Warning</b>";
       break;
       case E_USER_ERROR:
       case E_ERROR:
       $label = "<b>Fatal Error</b>";
       $notify=true;
       $halt_script = false;
       break;
       case E_PARSE:
       $label = "<b>Parse Error</b>";
       $notify=true;
       $halt_script = true;
       break;
       default:
       $label = "<b>Unknown Error</b>";
       break;
      }
      if($notify)
      {
       $msg = $label . $error_msg;
       echo $msg;
      }
      if($halt_script) exit -1;
    }
    $error_handler = set_error_handler("ErrHandler");
    echo "<BR><H2>Using Custom Error Handler</h2><BR>";
    trigger_error("<BR>Error caused by E_USER_NOTICE</BR>", E_USER_NOTICE);
    trigger_error("<BR>Error caused by E_USER_WARNING</BR>", E_USER_WARNING);
    trigger_error("<BR>Error caused by E_USER_ERROR</BR>", E_USER_ERROR);
    trigger_error("<BR>Error caused by E_PARSE</BR>", E_PARSE);
    ?>
