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 = $_FILES['file']; empty($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; }
