        <?php
       class Upload {

       private $allowedExts = array('doc','docx','pdf','txt','jpg','png');
       private $maxSize;
       private $file;
       private $uploadsDirecotry;
       private $fileUrl;
       private $filenames = array();

       function __construct($file,$allowedExts,$uploadsDirecotry,$maxSize){
           if(is_array($allowedExts) AND is_int($maxSize)){
             $this->file  = $file;
             $this->allowedExts = $allowedExts;
             $this->maxSize = $maxSize;
             $this->uploadsDirecotry = $uploadsDirecotry;

           }else{
             throw new Exception("File extension must be in an array and max size value must be intger value.");
           }

           }
       function uploadFiles(){

            $file = $this->file;
            $allowedExts = $this->allowedExts;
            $maxsize = $this->maxSize;
            $uploadsDir = $this->uploadsDirecotry;

        for($i = 0; $i < count($file['name']); $i++){

          $errors = array();

          // print_r($_FILES);
          $filename    = $file['name'][$i];
          $fileext    = strtolower(end(explode('.',$filename)));
          $filesize    = $file['size'][$i];
          $filetmpname = $file['tmp_name'][$i];

        if(in_array($fileext, $allowedExts) === FALSE){
           $errors[] = "Extension in sot allowed";
        }

         if($filesize > $maxsize){
            $errors[] = "File size must be less than {$maxsize} KB !";
         }

         if(empty($errors)){

            $random = rand(0,199);
            $this->fileUrl = $random . "_" . date("d-m-Y") . "_" . $filename;
            $destination = $uploadsDir. $random."_".date("d-m-Y") . "_" . $filename;
            move_uploaded_file($filetmpname, $destination);
            $this->filenames[] = $this->fileUrl;

         }else{

           foreach($errors as $error){
            throw new Exception($error);
           }
         }
              } // end for

              return TRUE;
       }

       function getFileUrl()
       {
             return $this->fileUrl;
           }

       function getFilesNames()
       {
             return $this->filenames;
           }

       }


    ?>

还有这个 html php 文件

        <?php include 'header.php';

                if(isset($_POST['add']))
                {
                    $e_title    = $_POST['e_title'];
                    $e_user     = $userRow['user_name'];    

                 try{
                    include 'models/Upload.php';
                    $file = $_FILES['e_img'];
                    $allowedExts = array('jpg','png','gif','jpeg');
                    $uploadsDirectory = "imgupload/";
                    $maxSize = 4000000;
                    $upload = new Upload($file, $allowedExts, $uploadsDirectory, $maxSize);
                    $upload->uploadFiles();
                    $e_img = $uploadsDirectory.$upload->getFileUrl();

                  }catch(Exception $exc){
                    echo'<div class="alert alert-block alert-danger">fail image uploaded</div>';
                    exit;}


                        $insert = $user->insert($e_title,$e_img,$e_user);

                        echo"<div class='alert alert-block alert-success'>Save success</div>";
                        exit;
            }

            ?>
                <form action='newads.php' method="POST" enctype="multipart/form-data">
                   <p>إضافة صور </p>
                    <input type="file" name='e_img[]' id="exampleInputFile">
                    <input  type="submit" name='add' class='btn btn-primary' value='add' />
              </form>


    <?php include 'footer.php'; ?>  

我试试这个，但是没有成功

    <form action='newads.php' method="POST" enctype="multipart/form-data">
    <p>إضافة صور </p>
    <input type="file" name='e_img[]' id="exampleInputFile">
    <input type="file" name='e_img2[]' id="exampleInputFile">
    <input type="file" name='e_img3[]' id="exampleInputFile">
    <input  type="submit" name='add' class='btn btn-primary' value='add' />
    </form>

您不需要增加文件字段中的字段名称。当 PHP 接收到它时，这将破坏数组。改成这个：（应该都是e_img[]

<input type="file" name='e_img[]' id="exampleInputFile">
<input type="file" name='e_img[]' id="exampleInputFile">
<input type="file" name='e_img[]' id="exampleInputFile">
