关于数组重组。该怎么处理

关于数组重组。

Array

(

    [0] => 123

    [1] => 456

    [2] => 789

)

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

能将上面这个数组，组装成下面的这个吗？



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













Array

(

    [0] => Array

        (

            [url] => 123

        )



    [1] => Array

        (

            [url] => 456

        )



    [2] => Array

        (

            [url] => 789

        )



)

------解决方案--------------------

foreach ($url as $url_value) {

$urls[] = array('url'=>$url_value);

}

------解决方案--------------------
另类的写法

$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
)

)
