PHP实现多图上传和单图上传功能
本文通过实例代码给大家介绍了基于PHP实现多图上传和单图上传功能,代码简单易懂,非常不错,具有一定的参考借鉴价值,需要的朋友可以参考下。
下面一段代码给大家介绍php实现单图上传和多图上传的功能,具体代码如下所示:
- /**
- * 多选图片上传
- *
- * @version v1.0.0
- * @author
- * @since 17-11-24
- */
- public function upload()
- {
- $file = $_FILES['file'];
- emptyempty($file) && $this->response(201,'请选择要上传的文件');
- unset($_FILES['file']);
- $count = count($file['name']); // 上传图片的数量
- $count > 10 && $this->response(203,'批量上传图片一次最多上传10张图片');
- $tmpFile = [];
- $returnData = [];
- for($i=0;$i<$count;$i++) // 循环处理图片
- {
- $tmpFile['name'] = $file['name'][$i];
- $tmpFile['type'] = $file['type'][$i];
- $tmpFile['tmp_name'] = $file['tmp_name'][$i];
- $tmpFile['error'] = $file['error'][$i];
- $tmpFile['size'] = $file['size'][$i];
- $_FILES['file_'.$i] = $tmpFile;
- // 判断是否是允许的图片类型
- $ext = substr($_FILES['file_'.$i]['name'],strrpos($_FILES['file_'.$i]['name'],'.')+1); // 上传文件后缀
- stripos('jpeg|png|bmp|jpg',$ext) === FALSE && $this->response(210,'图片格式支持 JPEG、PNG、BMP格式图片');
- $data = $this->uploadOne('file_'.$i,'jpeg|png|bmp|jpg');
- if($data['status'] == 1)
- {
- $this->response(500,'第'.($i+1).'张图片上传失败,'.$data['msg']);
- }
- $returnData[$i]['url'] = $data['url']; // 图片路径
- $returnData[$i]['old_name'] = substr($tmpFile['name'],0,strrpos($tmpFile['name'], '.')); // 图片原名称
- }
- $this->response(200,'successful',$returnData);
- }
- /**
- * 单文件上传
- * @version v1.0.0
- * @author
- * @since 17-11-24
- * @param $file 上传表单name名称
- * @param $type 上传类型
- * @param $maxSize 上传文件限制大小(默认 10M)
- */
- private function uploadOne($filename = 'file',$type = 'jpeg|png|bmp|jpg',$maxSize = 10240)
- {
- list($width,$height) = getimagesize($_FILES[$filename]['tmp_name']); // 获取图片的宽和高
- list($usec, $sec) = explode(" ", microtime());
- $time = $sec.substr($usec,2); // 秒数+微秒数
- $ext = substr($_FILES[$filename]['name'],strrpos($_FILES[$filename]['name'],'.')+1); // 上传文件后缀
- $name = $time.'-'.$width.'*'.$height.'.'.$ext;
- $filePath = $_FILES[$filename]['tmp_name'];
- $type = $_FILES[$filename]['type'];
- $this->load->library('Qiniu');
- $returnData['url'] = $this->qiniu->upload($name,$filePath,$type);
- $returnData['status'] = 0;
- return $returnData;
- }
