我在函数和插件小部件中有代码，请参见下面的代码。
function.php //显示计数

$n_format = number_format($n / 1000000000, 1) . \'B\';
} else if ($n > 999999) {
$n_format = number_format($n / 1000000, 1) . \'M\';
} else if ($n > 999) {
$n_format = number_format($n / 1000, 1) . \'K\';

请参见图片
我不明白，怎么修？
UPDATE
我的问题没有答案。我包括文件
widget-pop.php 到文件
function.php 在我的主题孩子。
如果使用localhost（Xampp），则可以正常工作。请访问我的网站radarsulselcom
谢谢
