php - 我怎样才能在循环外获取foreach循环变量

Question

这是wordpress自定义插件的代码。?

$pages = get_pages();
foreach ($pages as $page) {
  $pagee=$page->post_title;
}
echo $pagee; <---- I want here all pages name in variable.

请建议我该怎么做。

你只需像这样附加你的变量

$pages = get_pages();
$pagee = array();
foreach ($pages as $page) {
  $pagee[] = $page->post_title;
}
echo implode(",",$pagee);
