使用trigger_error怎么没有显示自定义的错误信息

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?phpfunction error($errorno,$errormes,$errorfile,$errorline){$error_info="错误信息：".$errorno."--".$errormes." in ".$errorfile." on line ".$errorline;echo $error_info;date_default_timezone_set("PRC");error_log("时间：".date("Y-m-d H:i:s")."-".$error_info."\r\n",3,"error_log.txt");die();}set_error_handler(error);$fp=fopen("aa.txt","r");if(!$fp){trigger_error("文件打不开");}else{echo"kai";}
Copy after login


运行后提示：
错误信息：2--fopen(aa.txt) [function.fopen]: failed to open stream: No such file or directory in D:\AppServ\www\test.php on line 10
为什么错误信息“fopen(aa.txt) [function.fopen]: failed to open stream: No such file or directory ”不是我用trigger_error定义的“文件打不开”，应该怎么改

------解决方案--------------------
set_error_handler(error);
===>
set_error_handler("error");
------解决方案--------------------
确认文件及路径正确了？ 当前目录下有aa.txt文件吗？
------解决方案--------------------
trigger_error("不能存在", E_USER_ERROR);

通常
trigger_error(）
set_error_handler('error_handler');
是配合使用，一个抛出，一个接受，处理
