public function getUserList($user_id){
$list_query = "SELECT ACTUAL_USER_ID FROM TABLE WHERE USER_ID = ".$user_id." ";
$result = parent::queryresult($list_query);
return $result;
}
foreach ($result as $uresult){ //$result contains user_id
$userlist[] = $classObject->getUserList($uresult['USER_ID']);
}
下面的循环输出
Array
(
[0] => Array
(
[0] => Array
(
[ACTUAL_USER_ID] => 133
)
)
[1] => Array
(
[0] => Array
(
[ACTUAL_USER_ID] => 122
)
)
)
我如何删除嵌套数组并使它像下面
Array
(
[0] => Array
(
[ACTUAL_USER_ID] => 133
)
[1] => Array
(
[ACTUAL_USER_ID] => 122
)
)
使用方括号[]访问数组的元素
foreach ($result as $uresult){ //$result contains user_id
$userlist[] = $classObject->getUserList($uresult['USER_ID'])[0];
}
编辑：在不同/旧版本的PHP上，您需要先将数组放入变量中：
foreach ($result as $uresult){ //$result contains user_id
$row = $classObject->getUserList($uresult['USER_ID']);
$userlist[] = $row[0];
}
