限制文件夾中的文件數量

Question

我在我的主機中有一個文件夾名稱/ clientupload /。我想限制clientupload文件夾及其子文件夾中的文件數量共計200.

我沒有任何想法如何做到這一點！

Answer 1

可以讓用戶上傳文件

香港專業教育學院改變了這一帶的子文件夾，工作前檢查（通過PHP）的文件量文件夾中。

例如（您可能需要更改有點didnt運行這個....）：

<?php 

    define("MAX_UPLOAD_AMOUNT", 200); 
    //switch to your dir name 
    $dirName = "/Temp/"; 
    //will count number of files 
    $totalFileAmount = countFiles($dirName); 

function countFiles($dirName){ 


    $fileAmount = 0; 
    //open dir 
    $dir = dir($dirName); 

    //go over the dir 
    while ($file = $dir->Read()){ 
    //check there are no .. and . in the list 
    if (!(($file == "..") || ($file == "."))){ 
     //check if this is a dir 
     if (Is_Dir($dirName . '/' . $file)){ 
      //yes its a dir, check for amount of files in it 
      $fileAmount += countFiles($dirName . '/' . $file); 
     } 
     else{ 
     //its not a dir, not a .. and not a . so it must be a file, update counter 
     $fileAmount++; 
     } 
    } 
    } 

    return $fileAmount; 
} 

    //check if user can upload more files 
    if ($totalFileAmount >= MAX_UPLOAD_AMOUNT) 
     echo "You have reached the upload amount limit, no more uploaded"; 
    else 
     echo "let the user upload the files, total number of files is $totalFileAmount"; 

    ?>

我發現我自己的工作解決方案！你可以嘗試下面的代碼。 200是您可以更改的文件限制！

<?php 

define("MAX_UPLOAD_AMOUNT", 200); 

function scan_dir($path){ 
    $ite=new RecursiveDirectoryIterator($path); 

    $bytestotal=0; 
    $nbfiles=0; 
    foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) { 

     $nbfiles++; 
     $files[] = $filename; 
    } 

    $bytestotal=number_format($bytestotal); 

    return array('total_files'=>$nbfiles,'files'=>$files); 
} 

$files = scan_dir('folderlinkhere'); 

if ($files['total_files'] >= MAX_UPLOAD_AMOUNT) 
     echo "Files are more than 200. "; 
    else 
      echo "Carry out the function when less than 200"; 
?>
