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:
$attach_size= 0;
if($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
?>
