php加入了类似的结果

我正在构建一个php通知系统（有点像facebook）

它的工作原理应该是，以我想要的方式列出所有事件。但我试图让它明白，如果它在同一篇文章中获得3+个事件，它将把这些事件合并到一个通知中

现在看起来是这样的：

User 1 wrote on article-x
User 2 wrote on article-x
user 3 wrote on article-x
user 1 wrote on article-y

Array
(
    [article-x] => Array
                   (
                       [0] => User1
                       [1] => User2
                   )
    [article-y] => Array
                   (
                       [0] => User1
                   )
)

$events = array();
foreach( $result as $row ) {
    if( isset($events[$row['article']) ){
        $events[$row['article']]['counter']++;
    }else{
        $row['counter'] = 0;
        $events[$row['article']] = $row;
    }
}

foreach( $events as $event ){
    echo "<div id='commentnote'>{$event['user']}".($event['counter']?' and '.$event['counter'].' others':'')." wrote on {$event['article']}</div>";
}

相反，我希望它像这样打印：

user 1 and  2 others wrote on article-x

我一直在努力了解我需要做什么，但运气不好。非常感谢您的指点。 它的查询方式如下：

User 1 wrote on article-x
User 2 wrote on article-x
user 3 wrote on article-x
user 1 wrote on article-y

Array
(
    [article-x] => Array
                   (
                       [0] => User1
                       [1] => User2
                   )
    [article-y] => Array
                   (
                       [0] => User1
                   )
)

$events = array();
foreach( $result as $row ) {
    if( isset($events[$row['article']) ){
        $events[$row['article']]['counter']++;
    }else{
        $row['counter'] = 0;
        $events[$row['article']] = $row;
    }
}

foreach( $events as $event ){
    echo "<div id='commentnote'>{$event['user']}".($event['counter']?' and '.$event['counter'].' others':'')." wrote on {$event['article']}</div>";
}

用完整代码编辑

$sesname=$\u会话['user\u name']；
$sesid=$\u会话['full\u name']；
$dbh=newpdo（“mysql:host=$hostname；dbname=$db”，$username，$password）；
$stmt=$dbh->prepare（“从注释中选择*，其中全名=“$sesid”和选中的“'1”）；
$stmt->bindParam（':full_name'，$safe_name，PDO:：PARAM_INT，5）；
$stmt->execute（）；
$result=$stmt->fetchAll（）；
foreach（$结果为$行）{
$name=$row['name']；
$pid=$row['pid']；
$commentid=$row['id']；
$fullink=$row['fullink']；
$datetime=$row['dt']；
如果（$name==$sesname）{
}否则{
echo“kommenterte ditt
x”；
}
}

尝试在下面使用你的答案，但没有运气。谢谢你的回答，我真的很感激：）

也许你可以创建这样一个二维数组：

User 1 wrote on article-x
User 2 wrote on article-x
user 3 wrote on article-x
user 1 wrote on article-y

Array
(
    [article-x] => Array
                   (
                       [0] => User1
                       [1] => User2
                   )
    [article-y] => Array
                   (
                       [0] => User1
                   )
)

$events = array();
foreach( $result as $row ) {
    if( isset($events[$row['article']) ){
        $events[$row['article']]['counter']++;
    }else{
        $row['counter'] = 0;
        $events[$row['article']] = $row;
    }
}

foreach( $events as $event ){
    echo "<div id='commentnote'>{$event['user']}".($event['counter']?' and '.$event['counter'].' others':'')." wrote on {$event['article']}</div>";
}

也许您可以创建一个二维数组，如下所示：

User 1 wrote on article-x
User 2 wrote on article-x
user 3 wrote on article-x
user 1 wrote on article-y

Array
(
    [article-x] => Array
                   (

                       [1] => User2
                   )
    [article-y] => Array
                   (
                       [0] => User1
                   )
)

$events = array();
foreach( $result as $row ) {
    if( isset($events[$row['article']) ){
        $events[$row['article']]['counter']++;
    }else{
        $row['counter'] = 0;
        $events[$row['article']] = $row;
    }
}

foreach( $events as $event ){
    echo "<div id='commentnote'>{$event['user']}".($event['counter']?' and '.$event['counter'].' others':'')." wrote on {$event['article']}</div>";
}

将文章转换为多维数组怎么样？（举个例子，结构不是最优的，因为我不知道您拥有和需要什么样的数据。）

如果要在PHP中执行此操作，请执行以下操作：

User 1 wrote on article-x
User 2 wrote on article-x
user 3 wrote on article-x
user 1 wrote on article-y

    [article-x] => Array

                       [0] => User1
                       [1] => User2
                   )
    [article-y] => Array
                   (
                       [0] => User1

        $events[$row['article']] = $row;
    }

foreach( $events as $event ){
    echo "<div id='commentnote'>{$event['user']}".($event['counter']?' and '.$event['counter'].' others':'')." wrote on {$event['article']}</div>";
}

$events=array（）；
foreach（$结果为$行）{
如果（isset（$events[$row['article']））{
$events[$row['article']['counter']++；
}否则{
$row['counter']=0；
$events[$row['article']]=$row；

foreach（$events作为$event）{
echo“{$event['user']}”。（$event['counter']？”和“$event['counter']。”其他“：”。”写在{$event['article']}上；
