统计用户收件箱所占空间有多少,先计算每封邮件的大小(标题+内容+附近),后总和;
1、计算附近大小;
2、计算标题和内容大小
3、总和求出单封邮件大小
案例:
复制代码 代码如下:
    $attach_size= 0;   
    if($attachmentid){  //获取附近的大小   
        $attach_data= attachdata($attachmentid);   
        if($attach_data){   
            foreach($attach_dataas$value) {   
                $attach_size+= $value['filesize'];   
            }   
        }   
    }   
    //获取标题和邮件内容的大小   
    $email_content_size= 0;   
    $_filename= "attachment/emailsizecalculate.tmp";   
    $_file= fopen($_filename, "wb");   
    fwrite($_file, $subject.$content);   
    fclose($_file);   
    if($_temp= filesize($_filename)){   
        $email_content_size= $_temp;   
    }   
    $del_ret= @unlink($_filename);   
    $sum_size= $attach_size*1024 + $email_content_size;  //邮件总大小          
?>
