复制代码 代码如下:

<?php

num = rand(1,5);

witch($num){

case 1:

$fp1=fopen("f1.dat",'r');

$oname = fgets($fp1);

$nname = date("YmdHis");

rename($oname,$nname);

fclose($fp1);

unlink("f1.dat");

$fp1=fopen("f1.dat",'w');

fwrite($fp1,$nname);

fclose($fp1);

header("Location: ".$nname."/1.html");

exit;

break;

case 2:

$fp2=fopen("f2.dat",'r');

$oname = fgets($fp2);

$nname = date("YmdHis");

rename($oname,$nname);

fclose($fp2);

$fp2=fopen("f2.dat",'w');

fwrite

fclose($fp2);

header("Location: ".$nname."/2.html");

exit;

break;

case 3:

$fp3=fopen

("f3.dat",'r');

刚做的一个项目中的部分代码，包含了php中随机数的产生、页面跳转、件读写、文件重命名、switch语句。

特发表出来，希望能对php学习者能够有所帮助。
