PHP: Move associative array element to beginning of array

Question

What would be the best method of moving any element of an associative array to the beginning of the array?

For example, say I have the following array:

Answer 1

if you have 2 arrays, 1st has elements to move to the top of 2nd array of elements, you can use

$result = \array_replace($ArrayToMoveToTop, $myArray);

Here is a code sample:

//source array    
$myArray = [
    'two' => 'Blah Blah Blah 2',
    'three' => 'Blah Blah Blah 3',
    'one' => 'Blah Blah Blah 1',
    'four' => 'Blah Blah Blah 4',
    'five' => 'Blah Blah Blah 5',
];
// set necessary order
$orderArray = [
    'one' => '',
    'two' => '',
];
//apply it
$result = \array_replace($orderArray, $myArray);
\print_r($result);
