本文实例讲述了PHP多文件上传类。分享给大家供大家参考。具体如下：代码如下:php/*PHP多文件上传类修改：Linvo 2008-2-15*/ class more_file_upload{const FILE_PATH='../upfileclass/uploadfile/';var $file_type;var $file_type_array;var $file_type_real_array;var $file_type_string;var $file_name;var $file_size;var $file_tmp_name;var $file_error;var $handledate;var $totalsize=0;function __construct($file_name,$file_error,$file_size,$file_tmp_name,$file_type){$this->handledate=date('m-d-Y');if (!empty($file_name)){$this->$file_name = $file_name;$this->$file_error = $file_error;$this->$file_size = $file_size;$this->$file_tmp_name = $file_tmp_name;$this->$file_type = $file_type;$this->$file_type_array = array('/', 'image/gif', 'image/jpg', 'image/jpeg', 'image/pjpeg', 'image/png');$this->$file_type_real_array = array(0.1, 'jpg'=>74707370, 'gif'=>7173, 'bmp'=>6677, 'png'=>807871);$this->show_execute_message($this->$file_error,$this->$file_name,$this->$file_type,$this->$file_size);}}function __destruct(){$this->$file_name = NULL;$this->$file_error = NULL;$this->$file_size = NULL;$this->$file_tmp_name = NULL;$this->$file_type = NULL;$this->$totalsize = 0;}function show_execute_message($smfileerror,$smfilename,$smfiletype,$smfilesize){if($smfileerror>0){switch ($smfileerror){case 1: $smfilemessage='文件超过服务器的约定大小！
