php post提交。有关问题

php post提交。问题
假如post提交：
user=name1&password1=123456&password2=123456
这样的连接 

我想name｛num｝  
num｛｝=1，2，3，4，5，6等等

这里的变量怎么写？
源码如下：

------解决方案--------------------
3楼被删？？
写个文件初始内容为1，post之前读取文件取出数值$num，得到name.$num，post之后把$num加1再写入这个文件
------解决方案--------------------
//post之前
$filenum="num.txt";
$fnum=fopen($filenum,"r");
if(!$num=fgetc($fnum))
{$num=0;}
.......你的操作
//post之后
$filenum="num.txt";
$fnum=fopen($filenum,"r");
if(!$num=fgetc($fnum))
{$num=0;}
else
{$num=intval($num)++;
fclose($fnum);
$fnumw=fopen($filenum,"w");
fwrite(fnumw,strval($num));
fclose($filenum);
}
?>
