Sort array by value and store in variable

问题

$array = array(5,4,6,8,5,3,4,6,1);

I want to sort $array like asort does, but the problem is that asort is a function and its product can't be stored in a variable.

How can I do something like this?:

$array = array(5,4,6,8,5,3,4,6,1);
$sorted_array = asort($array);

Edit: I also want $array to keep its original order.

回答1:

Do this for maintaining $array in its original order

$array = array(5,4,6,8,5,3,4,6,1);
$sorted_array = $array;
asort($sorted_array);

Output

回答2:

 $orignal_array = array(5,4,6,8,5,3,4,6,1);
 $copied_array = $orignal_array;

 asort($copied_array);
 $sorted_array = $copied_array;

 not the most efficient way to do it though :(

回答3:

Sort it first and then assign it

asort($array);
$sorted_array = $array
