PHP - reorder array by defined key to top

Question

I am trying to reorder a an array. Like

$array_to_reorder = array('home' => 'canada', 'school'=>'National School', 'phone' => '00808080', 'name'=>'john doe', '...'=>'...', '..'=>'...');
$shorting = array('name', 'phone', 'home');

I want to order $array_to_reorder as key defined in $shorting, and keep defined array to top of the array, and other array which was not defined at bottom.

I want this output:

$array_to_reorder = array(
'name'=>'john doe', 
'phone' => '00808080', 
'home' => 'canada', 
'school'=>'National School',
'...'=>'...', 
'..'=>'...'
);

post just example of how result should look like

After updating the question. You could flip array then use merge.

$array_to_reorder = array('home' => 'canada', 'school' => 'National School', 'phone' => '00808080', 'name' => 'john doe', '...' => '...', '..' => '...');
$shorting = array('name', 'phone', 'home');
$new_shorting = array_flip($shorting);
$result = array_merge($new_shorting, $array_to_reorder);

+1, this is what I'd have done, too. I've added the output and demo to your answer, but feel free to modify it as you see fit :)

but it will not work if that key has any value, like: name=>john doe, then it also stripe value. please tell me how to keep the value

@user007, I do not see any keys in the question.

sorry for that not writing the full array, here is the original array, array('name'=> 'johndoe', phone=>'08889898', 'home'=>'cananda', '..'=> '..');
