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;

 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);
