关于文本操作的几个问题~@~

你是想把留言写在一个文件中保存？
1。每次用追加的方式写入留言，留言之间需换行
2。每个留言的发言人、题目、内容等用特殊字符分隔
3。用下面函数读文件到一个数组中
array file ( string filename [, int use_include_path] )
4。数组每个元素为一条留言
5。用explode函数从留言中取出各字段信息
注意要有文件可写权限！

function readfromfile($file_name) {
$filenum=fopen($file_name,"r");
flock($filenum,LOCK_SH);
$file_data=fread($filenum,filesize($file_name));
fclose($filenum);
return $file_data;
}
function writetofile($file_name,$data,$method="w") {
$filenum=fopen($file_name,$method);
flock($filenum,LOCK_EX);
$file_data=fwrite($filenum,$data);
fclose($filenum);
return $file_data;
}
关键不是用二维数组,而是采用什么结构存贮数据
大多使用分隔符来实现如同数据库的多列储存
如 author||title||email||content||...
提取时每行读入再用 explode() 提取分列信息
test.php
_______________
<?
$array1 = file('test_data.php');
$attay2 = explode('||',$array1[0]);
echo $attay2[2];
?>
_____________
test_data.php
_____________
11||22||33||44||55
_____________
我的文件是这样的
   姓名：aaa||性别：bbb||email:lklklk||姓名：BBB||性别：BBB||email:lklkl||....就这样，我问的是怎么样用二维数组（其它方法也行）将内容值列出来，比如想要姓名为BBB的姓名，怎么办？要不是不是我的存储方法有问题？
这是所写的文本文件:

哦，天啊，太复杂了，看不懂的了，只要简单一点的，怎么样分行存储呢？用
\n 或 怎么不行啊？
