In what scenarios would using functions like array_splice and asort/arsort be beneficial for PHP developers, and how can they be implemented effectively to achieve the desired outcome in code?

Issue: When working with arrays in PHP, developers may need to remove specific elements or sort the array based on values. Functions like array_splice and asort/arsort can be beneficial in such scenarios to manipulate arrays efficiently. Code snippet: 

// Using array_splice to remove elements from an array
$fruits = array("apple", "banana", "cherry", "date");
array_splice($fruits, 1, 2); // Remove elements starting from index 1, remove 2 elements
print_r($fruits); // Output: Array ( [0] => apple [3] => date )

// Using asort to sort an array by values in ascending order
$numbers = array("3" => "three", "1" => "one", "2" => "two");
asort($numbers);
print_r($numbers); // Output: Array ( [1] => one [2] => two [3] => three )

// Using arsort to sort an array by values in descending order
$numbers = array("3" => "three", "1" => "one", "2" => "two");
arsort($numbers);
print_r($numbers); // Output: Array ( [3] => three [2] => two [1] => one )
