我有一个由成员在这里创建的函数。它在 PHP 文件中单独工作。但是，一旦我尝试在我的 Wordpress 模板中使用它（准确地说是 single.php），它就会停止工作（无论如何它都会输出 false）。当我试图在我的模板的 single.php 中使用它时，我已经包含了原始代码和代码。将不胜感激任何帮助。谢谢。
独奏：
<?php
// Normalize time to count from 0
function timeOfWeek($time) {
if (!is_int($time)) $time = strtotime($time) ;
$secondsInWeek = (7 * 24 * 3600);
return (($time - strtotime('monday 00:00')) % $secondsInWeek + $secondsInWeek) % $secondsInWeek;
}
function isOpen($opened, $time) {
$time = timeOfWeek($time);
foreach ($opened as $openday) {
list($open, $close) = $openday;
if ($open < $close) {
if ($time > $open && $time < $close) return true;
} else {
if ($time > $open || $time < $close) return true; // Special case sunday -> monday

return false;
