php文件操作

 1 <?php
 2     echo filetype(‘C:\WINDOWS\hh.exe‘).‘<br/>‘;
 3     $stt = stat(‘.\test.html‘);//打印该文件的属性细节
 4     print_r($stt);//返回为一个数组所以用print_r
 5     echo ‘<br/>‘;
 6 
 7     if(!@$f = fopen("a.txt", "r")){
 8         echo "This file isnot exist</br>";
 9         $num = 0;
10     }else{
11         $num = fgets($f, 10);
12         fclose($f);
13     }
14     $num++;
15     $f = fopen("a.txt", "w");
16     fwrite($f, $num);
17     fclose($f);
18     echo $num."<br/>";
19 ?>

2         $arr = scandir("c:/");    //    遍历目录函数
3     foreach ($arr as $v) {
4         if(!is_dir("c:/".$v)){    //判断是否为目录
5             echo $v."<br/>";
