此文件的文件名是 12321.php
报错如下：
Notice: Undefined index: fname in F:\php\www\12321.php on line 18
Notice: Undefined index: age in F:\php\www\12321.php on line 19
Notice: Use of undefined constant submit - assumed 'submit' in F:\php\www\12321.php on line 20
Notice: Undefined index: submit in F:\php\www\12321.php on line 20
日志里面也不会记录错误，页面里面也不会报错
谢谢你们的帮助，$_POST改成$_REQUEST和$_GET, $c=$_REQUEST[“submit”];还是会提示一下错误
otice: Undefined index: fname in F:\php\www\12321.php on line 18
Notice: Undefined index: age in F:\php\www\12321.php on line 19
Notice: Undefined index: submit in F:\php\www\12321.php on line 20
错误的这几行内容
$a=$_GET["fname"];
$b=$_GET["age"];
$c=$_REQUEST[“submit”];
