文件操作_遍历操作文件夹内所有文件

文件遍历函数：read_directory

 1 function read_directory($dir,$floor=0)
 2 {
 3    
 4     if(!is_dir($dir))
 5     {
 6         return false;
 7     }
 8     $handir=opendir($dir);
 9     while(($row=@readdir($handir))!==false)
10     {
11         
12         $floor?$line=$floor-20:$floor=0;
13         if($row!='.'&&$row!='..')
14         {
15            
16             if(is_file($dir.'/'.$row))
17             {
18                 if($floor>20)
19                 {
20                     echo "<span style='display:block;float:left;".$floor."px;'><div style='".$line."px;height:20px;border-right:1px solid #000;float:left;'></div>--</span>";
21                     echo "文件:".$dir.'/'.$row."<br/>";
22                 }
23                 else
24                 {
25                     echo "文件:".$dir.'/'.$row."<br/>";
26                 }
27             }
28             else
29             {
30                 
31                 if($floor>20)
32                 {

34                     echo "目录:".$row."<br>";
35                     $func=__FUNCTION__;
36                     $endfloor=$floor+20;
37                     $func($dir.'/'.$row,$endfloor);  
38                 }
39                 else
40                 {
41                     
42                     echo "目录:".$row."<br>";
43                     $func=__FUNCTION__;
44                     $endfloor=$floor+20;
45                     $func($dir.'/'.$row,$endfloor);
46                 }
47             }
48         }
49     }
50 }

内容替换函数：rep

 1 function rep($reg){
 2     $redata = [
 3       '/css//' => "__CS__/",
 4       '/js//' => "__JS__/",
 5       '/images//' => "__IMG__/",
 6       '/picture//' => "__PIC__/",
 7       '/gif//' => "__GIF__/"
 8     ];
 9     $content=file_get_contents($reg);
10     $arr=[];
11     foreach($redata as $pat=>$text)
12     {
13         preg_match_all($pat,$content,$arr);
14         var_dump($arr);
15         foreach($arr[0] as $key=>$val)
16         {
17             $content = preg_replace($pat,$text,$content);
18         }
19     }
20 
21     file_put_contents($reg,$content);
22 }
