我正在尝试组合
<?php
$names = $xml->xpath("/server/game/players/player[disconnect_time = '']/name");
$connect_times = $xml->xpath("/server/game/players/player[disconnect_time = '']/connect_time");
?>
<?php
foreach ($names as $name)
{
echo $name . "<br />";
}
foreach ($connect_times as $connect_time)
{
echo $connect_time . "<br />";
}
?>
使它们相互连接，如:
$name1 - $connect_time1
$name2 - $connect_time2
$name3 - $connect_time3
但是现在它只是按顺序回显出来，就像
美元name1
美元name2
美元name3
美元connect_time1
美元connect_time2
美元connect_time3
我不太擅长使用foreach -所以我希望在这里得到一些指导。保持xpath很重要，因为我只想显示disconnect_time为空的玩家，因为这意味着他们仍在游戏中。(XML存储最近的玩家一段时间)
提前非常感谢!
编辑:哦!有可能在connect_time中添加一个小时吗?它比应该显示的时间晚了一个小时。我有这段代码-但是再一次，不知道如何将它与其他代码结合起来…
$connect_time = date("Y-m-d H:i",strtotime("+1 hour",strtotime($name)));
$first = new DateTime("now");
$second = new DateTime($connect_time);
$diff = $first->diff( $second );
编辑2:添加XML的内容以进一步帮助获得解决方案。谢谢你的帮助!
<server>
<game>
<players>
<player>
<name>Player 1</name>
<connect_time>2014-03-15 09:05</connect_time>
<disconnect_time/>
</player>
<player>
<name>Player 2</name>
<connect_time>2014-03-15 09:21</connect_time>
<disconnect_time>2014-03-15 09:58</disconnect_time>
</player>
<player>
<name>Player 3</name>
<connect_time>2014-03-15 09:39</connect_time>
<disconnect_time/>
</player>
<player>
<name>Player 4</name>
<connect_time>2014-03-15 09:50</connect_time>
<disconnect_time>2014-03-15 10:00</disconnect_time>
</player>
</players>
</game>
</server>
IMO，解决方案是选择<player> -节点并访问foreach内部的子节点:
$players = $xml->xpath("/server/game/players/player[disconnect_time = '']");
foreach ($players as $player) {
echo $player->name . " - " . date("Y-m-d H:i", strtotime($player->connect_time) + 3600) . PHP_EOL;
}
