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：

<?phperror_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。
