Are there alternative methods or functions in PHP that could be more efficient for achieving the desired array transformation?

The issue with the current code is that it uses nested loops to transform the array, which can be inefficient for large arrays. One alternative method to achieve the desired array transformation more efficiently is to use the array_map() function in PHP. This function applies a callback function to each element of the array and returns a new array with the modified elements. 

// Original array
$array = [
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
    ['name' => 'Mike', 'age' => 35]
];

// Using array_map to transform the array
$transformedArray = array_map(function($person) {
    return ['fullName' => $person['name'], 'yearsOld' => $person['age']];
}, $array);

// Output the transformed array
print_r($transformedArray);
