How can PHP arrays be efficiently cleaned of specific values or characters?

To efficiently clean PHP arrays of specific values or characters, you can use array_filter() function along with a custom callback function that removes the unwanted values. This allows you to filter out elements based on a condition you specify, effectively cleaning the array. 

// Original array
$array = array("apple", "banana", "cherry", "apple", "orange");

// Function to remove specific value "apple"
function filterApple($value){
    return $value !== "apple";
}

// Cleaning the array
$cleanedArray = array_filter($array, "filterApple");

// Output cleaned array
print_r($cleanedArray);
