What are some common sorting algorithms in PHP that can be used to organize an array of variables?

When working with arrays in PHP, it is often necessary to sort the elements in a specific order. PHP provides several built-in sorting functions that can be used to organize an array of variables. Some common sorting algorithms in PHP include sort(), rsort(), asort(), ksort(), and usort(). These functions allow you to sort arrays in ascending or descending order, based on values or keys, and even define custom sorting criteria.

// Example of sorting an array using the sort() function
$numbers = array(4, 2, 8, 5, 1);
sort($numbers);
print_r($numbers);
