如何使用PHP向多个用户发送消息

Question

我正在使用PHP消息系统在用户之间发送消息。但我的问题是，如何将消息发送给new_pm.php中的多个用户。

$dn1 = mysqli_fetch_array($conn->query('select count(id) as recip, id as 
recipid, (select count(*) from pm) as npm from registrationform where 
email="'.$recip.'" ')); 

if($conn->query('insert into pm (id, id2, title, user1, user2, message, 
timestamp, user1read, user2read)values("'.$id.'", "1", "'.$title.'", 
"'.$id1.'", "'.$dn1['recipid'].'", "'.$message.'", "'.time().'", "yes", 
"no")')) 

Answer 1

伪代码：

的foreach user2array为用户
做你的插入查询，但用户2列，替换为目标用户ID值。

什么是id2列我不确定。也许你可以弄明白。
