Question

假设我有一个这样的数组：

$myarray = attr_group => array(
             "group_id" => array(
                    "attr" => array(
                          [0] => "test1"
                          [1] => "test2"
                          [3] => "test1,test2,test3,test4"
                          [4] => "test1,test5,test6"
                     )
               )
           )

如何将“attr”数组中的值分解到不同的行，然后继续使用数组，如果我这样调用它：

$myarray[attr_group][group_id][attr]

我希望我的数组的最终结果看起来像这样：

$myarray = attr_group => array(
             "group_id" => array(
                    "attr" => array(
                          [0] => "test1"
                          [1] => "test2"
                          [3] => "test3"
                          [4] => "test4"
                          [5] => "test5"
                          [6] => "test6"
                     )
               )
           )

也许这不可能，但我认为值得发帖！提前谢谢！

$myarray = array(
    "attr_group" => array(
        "group_id" => array(
            "attr" => array(
                0 => "test1",
                1 => "test2",
                3 => "test1,test2,test3,test4",
                4 => "test1,test5,test6"
            )
        )
    )
);

$attr = &$myarray["attr_group"]["group_id"]["attr"];
$attr = array_values(array_unique(explode(",", implode(",", $attr))));

print_r($myarray);
