How to remove empty elements from an array in PHP

PHP has a built-in array_filter() function by using that we can remove the empty elements from an array.

Here is an example, that removes the empty strings from a given array.

$fruits = array("apple", "", "avocado", "grapes", 20, "","");

print_r(array_filter($fruits));

Output:

Array
(
    [0] => apple
    [2] => avocado
    [3] => grapes
    [4] => 20
)
