Php 将WP循环分解为函数

我试图将一个简单的foreach循环分解为两个函数：start和end

functions.php：

function days_start() {
  $days = [];
  $meals_monday = get_field('monday_meal');
  $meals_tuesday = get_field('tuesday_meal');
  $meals_wednesday = get_field('wednesday_meal');
  $meals_thursday = get_field('thursday_meal');
  $meals_friday = get_field('friday_meal');
  $meals_saturday = get_field('saturday_meal');
  $meals_sunday = get_field('sunday_meal');
  array_push($days, $meals_monday, $meals_tuesday, $meals_wednesday, $meals_thursday, $meals_friday, $meals_saturday, $meals_sunday);

  foreach( $days as $day ):
}

function days_end() {
  endforeach;
}

我这样做是为了在不重写的情况下多次使用它。但是，我得到了这个错误：

"syntax error, unexpected '}'"

我想我一定是瞎了，但我不明白为什么会出现这种情况。或者在函数内部使用foreach函数而不关闭它是不可能的

谢谢

好的，我从函数中删除了foreach语句，并执行了以下操作：

functions.php

function days_before_loop() {
  global $days;

  $days = [];
  $meals_monday = get_field('monday_meal');
  $meals_tuesday = get_field('tuesday_meal');
  $meals_wednesday = get_field('wednesday_meal');
  $meals_thursday = get_field('thursday_meal');
  $meals_friday = get_field('friday_meal');
  $meals_saturday = get_field('saturday_meal');
  $meals_sunday = get_field('sunday_meal');
  array_push($days, $meals_monday, $meals_tuesday, $meals_wednesday, $meals_thursday, $meals_friday, $meals_saturday, $meals_sunday);

  return $days;
}

那么就这样称呼它：

days_before_loop();
foreach( $days as $day ):
  // do some stuff
endforeach();

嗯，你总是需要关闭所有的东西。我明白，但有可能在一个功能中打开，在另一个功能中关闭吗？据我所知，没有其他方法来管理它吗？所以要重复使用循环的开始和结束？我不确定我是否理解这样做的必要性它的目的所以我帮不上忙。嗯，你总是需要关闭所有东西。我理解，但有可能在一个功能中打开，在另一个功能中关闭吗？据我所知，这将是混乱的，有其他的方法来管理吗？所以要重复使用循环的开始和结束？我不确定我是否理解这样做的必要性它的目的所以我几乎帮不上忙。
