What are the different options for sorting arrays in PHP and when should each be used?

There are several options for sorting arrays in PHP, including using functions like sort(), rsort(), asort(), ksort(), and usort(). - sort() sorts an array in ascending order based on its values - rsort() sorts an array in descending order based on its values - asort() sorts an array in ascending order based on its values, while maintaining key-value associations - ksort() sorts an array in ascending order based on its keys - usort() allows for custom sorting using a user-defined comparison function Here is an example of using the sort() function to sort an array in ascending order:

$numbers = array(4, 2, 8, 6, 3);
sort($numbers);
print_r($numbers);
