php功能使发送多张图片更加容易

如何解决php功能使发送多张图片更加容易

我正在尝试防止冗余，是否有办法让每个图像通过一个函数以使代码看起来不太冗余和整洁，是否有办法将每个图像发送到一个代码块中，有效

$filename_1 = basename($_FILES["product_image_1"]["name"]); 
 if(!empty($_FILES["product_image_2"]["name"])){ 
 $filename_2 = basename($_FILES["product_image_2"]["name"]); 
 }
 if(!empty($_FILES["product_image_3"]["name"])){ 
 $filename_3 = basename($_FILES["product_image_3"]["name"]); 
 }
 if(!empty($_FILES["product_image_4"]["name"])){ 
 $filename_4 = basename($_FILES["product_image_4"]["name"]); 
 }
 if(!empty($_FILES["product_image_5"]["name"])){ 
 $filename_5 = basename($_FILES["product_image_5"]["name"]); 
 }
 if(!empty($_FILES["product_image_6"]["name"])){ 
 $filename_6 = basename($_FILES["product_image_6"]["name"]); 
 }

 $allowTypes = array('pdf','doc','docx','jpg','png','jpeg'); 
 $images="";
 if(!empty($filename_1)){
 $fileName_1 = (time()). '-' .rand(0,100000000).'.png';
 // echo $fileName_1;  
 $images.= "$fileName_1,";
 $targetFilePath = $uploadDir . $fileName_1;
 $fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION); 
          if(in_array($fileType,$allowTypes)){ 
     // Upload file to the server 
     if(copy($_FILES["product_image_1"]["tmp_name"],$targetFilePath)){ 
        $product_image_1=$fileName_1;
        if($product_image_1==''){
            $error= 'Image not uploaded';
        }

      }

                     } 
         } 
    }

}

也许是一个循环或多个循环或类似的东西？ 任何帮助都会逐渐得到赞赏
