Are there any specific PHP functions or methods that can be used to extract and sort last names from a combined name column in a database?

To extract and sort last names from a combined name column in a database, you can use the PHP explode() function to split the full name into an array of first and last names. Then, you can use array_column() to extract the last names and sort them alphabetically using the sort() function. 

// Assuming $names is an array of combined names from the database
$lastNames = [];
foreach ($names as $name) {
    $parts = explode(' ', $name);
    $lastNames[] = end($parts);
}

sort($lastNames);

print_r($lastNames);
