在PHP中输出一个数组，在数组中输出数组

Question

I only want to output an array, first look at my code

CODE:

$shopping = array();
$shopping["john"] = "notebook1";
$shopping["john"] = "notebook2";
$shopping["doe"] = "notebook3";

echo '<pre>';
print_r($shopping);
echo '</pre>';

OUTPUT

    Array
(
    [john] => notebook2
    [doe] => notebook3
)

But I want my output to be like this:

    Array('john'=>array('notebook1','notebook2'),'doe'=>'notebook3');

How Can I achieve this?

Answer 1

Just need to assign $shopping["john"] to an array.

$shopping["john"] = array("notebook1", "notebook2");
$shopping["doe"] = "notebook3";
