TP3.2 二進制存儲信息

以組裝郵件附件爲例

//version[固定100]: 一共幾組附件:itemid:number:itemid:number 組裝格式
//100:2:100001:10:100002:20
if (!empty($value['send_items'])) { 
    $serverMail['items'] = '';
    $send_items = json_decode($value['send_items'],true);
    $version = '100';
    $count = count($send_items); 
    $serverMail['items'] .=pack('ii',$version,$count);  
    foreach ($send_items as $key1 => $value1) {  
        $serverMail['items'] .= pack('ii',$value1['code'],$value1['num']); 
    }  
}else {
    //沒有附件二進制文件組成100:0 
    $serverMail['items'] = pack('ii','100', '0'); 
}
