    ▪php 随机数的产生、页面跳转、件读写、文件重命名、switch语句       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); .........

    ▪PHP 远程文件管理，可以给表格排序，遍历目录，时间排序       代码如下: <?php $rootdir="./"; $spacenum=0; $filenum=0; $allfilesize=0; echo "<h1>文件管理调试测试</h1>"; echo "<a href=''>重置</a>"; readLogDir($rootdir); echo "<hr>"; echo "Total files count: $filenum.........

    ▪PHP 翻页 实例代码       代码如下: <?php class Page { private $pageSize;//每一页多少行 private $absolutePage;//当前页 private $pageCount;//总页码数 private $totalNum;//总行数 private $prePage;//上一页 private $nextPage; //下一页 private $sqlStr;.........

fclose($fp1);
unlink("f1.dat");
$fp1=fopen("f1.dat",'w');
fwrite($fp1,$nname);
fclose($fp1);

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

exit;
