What is the fastest way to assign the correct types to values in an array consisting only of strings in PHP?

When working with an array consisting only of strings in PHP, the fastest way to assign the correct types to values is to use the array_map function along with the appropriate type-casting functions. This allows you to quickly iterate over each value in the array and cast it to the desired type, such as integer or float. 

// Sample array consisting only of strings
$array = ['10', '20', '30.5', '40'];

// Use array_map to apply type-casting functions to each value in the array
$array = array_map('intval', $array); // Casts each value to an integer

// Output the updated array with correct types
print_r($array);
