PHP 严格标准:只有变量应该通过引用传递 // array_pop
PHP Strict Standards: Only variables should be passed by reference // array_pop
因为我在 PHP 5.6,所以我有这个警告(不在 PHP 5.2):
PHP Strict Standards: Only variables should be passed by reference in blockcategories_top.php on line 157
这是第 157 行:
line 155 if ($cookie->last_visited_category) {
line 156 $c = new Category(intval($cookie->last_visited_category));
line 157 $oldies = array_pop($c->getParentsCategories());
line 158 $oldies = $oldies['id_category'];
line 159 $smarty->assign('oldies', $oldies);
line 160 }
拜托,我该如何解决? :)
谢谢!
