php的文件上传

总结一下文件上传：

先对表单做个说明吧：

enctype="multipart/form-data"//这个才支持文件上传<pre style="background-color:#ffffff;color:#000000;font-family:'宋体';font-size:12pt;"><span style="background-color:#efefef;"></span><pre name="code" class="html"><input type="file"  class='text' data-container="body" data-trigger="focus" data-placement="right" data-content="预览图" id="homeimg1" name="homeimg1"  />

然后这个要用到php的超全局变量$_FILES

print_r($_FILES);

Array(

[homeimg1] => Array ([name] => ssss.jpg [type] => image/jpeg [tmp_name] => C:\temp\phpD160.tmp [error] => 0 [size] => 424112 )

[homeimg2] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 )

[homeimg3] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 )

[homeimg4] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 )

[homeimg5] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 )

)

<pre name="code" class="php">for($i=1;$i<6;$i++){            if(is_uploaded_file( $_FILES['homeimg'.$i]['tmp_name'])){                $photoname = $this->upload_fang($_FILES['homeimg'.$i],$i,$arr['id']);                $arr['img'.$i] = $photoname;            }        }

 public function upload_fang($file,$i,$NOwnewid){        //照片上传        $photo_types=array('image/jpg', 'image/jpeg','image/png','image/pjpeg','image/gif','image/bmp','image/x-png');//定义上传格式        $max_size=3000000;    //上传照片大小限制,默认3M//        $photo_folder="/sda1/tomcat7/webapps/ROOT/pinggu/move/pic/"; //上传照片路径 linux        $photo_folder="AAA/"; //上传照片路径 windwon        if(!in_array($file['type'],$photo_types)){            echo "上传图片类型不符合标准，请重新选择";            exit;        }        if($max_size<$file['size']){            echo "上传图片过大，请重新选择";            exit;        }        $photo_name=$file["tmp_name"];        if(!file_exists($photo_folder))//照片目录            mkdir($photo_folder);        $pinfo=pathinfo($file["name"]);        $photo_type=$pinfo['extension'];//上传文件扩展名        $photo_server_folder = $photo_folder."f".$NOwnewid.$i.".".$photo_type;//以当前时间和7位随机数作为文件名，这里是上传的完整路径        if(!move_uploaded_file ($photo_name, $photo_server_folder))        {            echo "移动文件出错";            exit;        }        return "f".$NOwnewid.$i.".".$photo_type;    }
