關於數組重組。該怎麼處理

關於數組重組。

Array
(
    [0] => 123
    [1] => 456
    [2] => 789
)
$url = array('123','456','789');
能將上面這個數組，組裝成下面的這個嗎？

$urls = array(array('url'=>'123'),array('url'=>'456'),array('url'=>'789'));






Array
(
    [0] => Array
        (
            [url] => 123
        )

    [1] => Array
        (
            [url] => 456
        )

    [2] => Array
        (
            [url] => 789
        )

)

------解決方案--------------------

foreach ($url as $url_value) {
$urls[] = array('url'=>$url_value);
}

------解決方案--------------------
另類的寫法

$ar = array(123, 456, 789);
$t = array_map('array_combine',array_chunk(array_fill(0,count($ar), 'url'), 1), array_chunk($ar, 1));
print_r($t);

Array
(
[0] => Array
(
[url] => 123
)

[1] => Array
(
[url] => 456
)

[2] => Array
(
[url] => 789
)

)
