知道要被程序员大佬们笑掉大牙了，但实在是搞不懂了，
正在做一个网站，希望能通过 PHP 调用 steam 上某款游戏的实时在线人数，所以在网上找了一段代码：
<?php
$str=file_get_contents('https://steamcommunity.com/app/200210');
if ($x=strpos($str,'<span class="apphub_NumInApp">')) $str=substr($str,$x);
if ($x=strpos($str,'</span>')) $str=substr($str,0,$x);
echo $str;
?>
这样倒是可以调取我要的内容了，但是输出的是
<span class=”apphub_NumInApp“>1,910 In-Game
怎么改才能不要前边的 [ <span class=”apphub_NumInApp“> ] 呢？谢谢
