php - 限制文件夹中的文件数

Question

我的主机中有一个文件夹名称 /clientupload/。我想将 clientupload 文件夹及其子文件夹中的文件数限制为 200 个。

我不知道该怎么做！

Answer 1

在让用户上传文件之前，您可以检查（通过 php）文件夹中的文件数量

我将其更改为与子文件夹一起使用。

例如（你可能需要改变一点没有运行这个......）：

<?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"; 

  ?>

我自己找到了一个可行的解决方案！你可以试试下面的代码。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";
?>
