How can PHP developers ensure data consistency and scalability when dealing with dynamic data manipulation tasks like adding and deleting entries in arrays?

When dealing with dynamic data manipulation tasks like adding and deleting entries in arrays, PHP developers can ensure data consistency and scalability by using locking mechanisms to prevent race conditions and implementing proper error handling to handle any potential issues that may arise during the manipulation process. 

// Example code snippet demonstrating how to ensure data consistency and scalability when adding and deleting entries in arrays

// Lock the array to prevent race conditions
$lock = fopen("lockfile.lock", "w");
if (flock($lock, LOCK_EX)) {
    // Perform array manipulation tasks here
    $array = [1, 2, 3];
    $array[] = 4; // Add entry
    unset($array[1]); // Delete entry

    flock($lock, LOCK_UN); // Release the lock
} else {
    echo "Unable to acquire lock, please try again later.";
}

fclose($lock);
