How can array_map be utilized in PHP to reassemble data after processing it into separate arrays?

When processing data into separate arrays using array_map in PHP, you may need to reassemble the data back into a single array. To do this, you can use array_map again with a custom callback function that combines the separate arrays into one. 

// Separate arrays
$array1 = [1, 2, 3];
$array2 = ['a', 'b', 'c'];

// Process the arrays
$processedArray1 = array_map(function($item) {
    return $item * 2;
}, $array1);

$processedArray2 = array_map(function($item) {
    return strtoupper($item);
}, $array2);

// Reassemble the data
$combinedArray = array_map(function($item1, $item2) {
    return $item1 . $item2;
}, $processedArray1, $processedArray2);

print_r($combinedArray);
