What are the best practices for handling string manipulation in PHP arrays to avoid script inefficiencies?

When manipulating strings within PHP arrays, it is important to avoid inefficient practices such as using nested loops or excessive array functions. Instead, consider using built-in PHP functions like array_map or array_walk to apply string manipulation functions to array elements efficiently. 

// Example of using array_map to apply string manipulation function to array elements
$array = ["apple", "banana", "cherry"];
$modifiedArray = array_map('strtoupper', $array);
print_r($modifiedArray);
