PHP 实现一种多文件上传的方法

<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 . '_split_' . $j); } }else{ array_push($arrayFile, $field); } //遍历file多个文件 上传 foreach($arrayFile as $file){ if (isset($_FILES[$file]) && $_FILES[$file]['name']) { //自定义上传方法 具体内容略 $data = $this->uploadFile($file, $path, uniqid());    if ( isset($data) && !empty($data) ) {      if(!isset($data['errors'])){        //将上传结果存储于$result中 多图片地址使用逗号拼接        if(isset($result)){          $result = array('errorCode'=>0, 'message'=>$result['message'] . ',' . reset($data));        }else{          $result = array('errorCode'=>0, 'message'=>reset($data));        }      }else{        //以下为返回错误信息        if(is_array(reset($data))){          $message = reset($data)[0];        }else{          $message = reset($data);        }                   $result = array('errorCode' => 1, 'message' => $message);      }    } else {      $result = array('errorCode'=>1, 'message'=>'上传失败');      break;    }  } else {    $result = array('errorCode'=>1, 'message'=>'请上传文件');    break;  }}//返回上传结果return $result;
