如何从这段代码中获取数组数据？

我只是不明白的代码可以正确，从阵列获取数据。

Answer 1

在代码的结尾（类结束后），通过这个替换的代码：

$cstrike = new cstrike_statistics(); 
$cstrike->setHostname("206.212.247.10"); 
$cstrike->setPort(27015); 

$result = $cstrike->getData(); 

//For maxplayers, do this: 
echo "<h3>Maximum Players: ".$result['cstrike']['ServerVars']['maxplayers']."</h3>"; 

//For players do this: 
foreach($result['cstrike']['ServerInfo'] as $players) 
    echo "<h4>Player Name: ".$players['name']."</h4>"; 

Answer 2

也许最好通过对数组手册页改为：http://php.net/manual/en/language.types.array.php

Answer 3

尝试以下：

$obj = $cstrike->getData(); 
echo "players count : " . count($obj['cstrike']['ServerInfo']) . "<br/>"; 
echo "Player1 Name: " . $obj['cstrike']['ServerInfo'][0]['name'] . "<br/>";
