複数ファイルのアップロードをphpで実装する方法

<input type="file" id="image" class="file image hidden" name="image[]" multiple="true">

{"name":"7332.png","type":"image\/png","tmp_name":"\/tmp\/phplqppvR","error":0,"size":659}

{"name":["7656.png","7718.png"],"type":["image/png","image/png"],"tmp_name":["/tmp/phpDzSovj","/tmp/phpP8kWmT"],"error":[0,0],"size":[357,662]}

if (!isset($_FILES[$field])) {
  return new JsonResponse(array('errorCode'=>1, 'message'=>'请上传文件'));
}
//重新命名$_FILE 存储多个文件上传
$arrayFile = array();
foreach($_FILES[$field] as $key => $value){
  $i = 0;
  if(is_array($value)) {
    foreach ($value as $v) {
      $i++;
      //重命名后重新放入超全局变量_FILE 保证键名唯一 也可直接上传
      $name = $field . '_split_' . $i;
      $_FILES[$name][$key] = $v;
    }
  }
}
//是否上传多文件
if($i > 0){
  for($j = 1; $j <= $i; $j++){ array_push($arrayFile, $field . &#39;_split_&#39; . $j); } }else{ array_push($arrayFile, $field); } //遍历file多个文件 上传 foreach($arrayFile as $file){ if (isset($_FILES[$file]) && $_FILES[$file][&#39;name&#39;]) { //自定义上传方法 具体内容略 $data = $this->uploadFile($file, $path, uniqid());
