Php 注意：从函数数组到字符串的转换我无法从其他问题中得到答案

注意：第128行C:\xampp\htdocs\dysway\manager\offices.php中的数组到字符串转换 排列

但是当我尝试的时候

(!function_exists('get_office_status')) {
    function get_office_status(){
    global  $lang;
    return Array
    (
        1 => array( 1,$lang['head']),
        2 => array( 2,$lang['branch']),
    );
  }
}

我试图创建的带有数组的函数n

$lang = array();

$lang = array_merge($lang,array(
 "head"             => "Head",
 "branch"           => "Branch",
));

感谢BangingHeads@

(!function_exists('get_office_status')) {
    function get_office_status(){
    global  $lang;
    return Array
    (
        1 => array( 1,$lang['head']),
        2 => array( 2,$lang['branch']),
    );
  }
}

$lang = array();

$lang = array_merge($lang,array(
 "head"             => "Head",
 "branch"           => "Branch",
));

if(!function_exists('get_office_status')) {
    function get_office_status(){
    global  $lang;
    return Array
    (
        1 => $lang['head'],
        2 => $lang['branch']
    );
  }
}
