Remove Empty Array Elements in PHP

In PHP, you can use the array_filter() function to remove empty elements from an array. Here is an example:

$array = array("apple", "", "orange", "", "banana");

$filtered_array = array_filter($array);

print_r($filtered_array);

The output result is:

Array
(
    [0] => apple
    [2] => orange
    [4] => banana
)

In the example above, the array_filter() function will filter out empty elements and return a new array.
