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);
?>
