限制文件夹中的文件数量

在允许用户上传文件之前，您可以(通过php)检查文件夹中的文件数量

ive将此更改为与子文件夹一起工作。

(您可能需要更改一点没有运行此....):

<?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!您可以尝试下面的代码。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";
?>
