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);
- ?>
希望本文所述对大家的php程序设计有所帮助。
