How can whitespaces be removed and empty array elements be deleted in PHP?

To remove whitespaces and delete empty array elements in PHP, you can use a combination of functions like array_filter() and trim(). The array_filter() function will remove empty elements from the array, and the trim() function will remove whitespaces from the beginning and end of each element. 

// Sample array with whitespaces and empty elements
$array = array("  apple ", "banana", "  ", "  orange  ", "");

// Remove whitespaces and empty elements
$array = array_filter(array_map('trim', $array));

// Output the cleaned array
print_r($array);
