Output of this all is :

I just can't understand the code properly to get data from array.

At the end of the code (after the class ends), replace the code by this:

$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>";

Probably best to read through the manual page on arrays: http://php.net/manual/en/language.types.array.php

Try the below:

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