Question

我正在上传多个文件。主要功能正常，但我必须更改上传文件的名称，如： name1.jpg，name2.jps，name3.jpg，...

$i = 1;
if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/name'.$i++.'.'.$extension)){
     echo '{"status":"success"}';
     exit;
}

数字$i应随着上传文件的数量而增长。我希望能正确解释。

正如@Ghost在评论中所说，你需要一个循环：

if(isset($_FILES['files'])){

     $name_array = $_FILES['files']['name'];
     $tmp_name_array = $_FILES['files']['tmp_name'];
     // Number of files
     $count_tmp_name_array = count($tmp_name_array);

     // We define the static final name for uploaded files (in the loop we will add an number to the end)
     $static_final_name = "name";

     for($i = 0; $i < $count_tmp_name_array; $i++){
          // Get extension of current file
          $extension = pathinfo($name_array[$i] , PATHINFO_EXTENSION);

          // Pay attention to $static_final_name 
          if(move_uploaded_file($tmp_name_array[$i], "uploads/".$static_final_name.$i.".".$extension)){
               echo $name_array[$i]." upload is complete<br>";
          } else {
               echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
          }

     }

}
