In PHP, how do I sort arrays with built-in functions?

In PHP, you can sort arrays using several built-in functions. Here are a few commonly used functions for sorting arrays:

  • sort() - Sorts an array in ascending order.
  • rsort() - Sorts an array in descending order.
  • asort() - Sorts an associative array in ascending order, according to the value.
  • arsort() - Sorts an associative array in descending order, according to the value.
  • ksort() - Sorts an associative array in ascending order, according to the key.
  • krsort() - Sorts an associative array in descending order, according to the key.

Here is an example of sorting a simple array in PHP:

<?php $numbers = array(4, 2, 8, 6, 1); sort($numbers); echo "Sorted numbers: "; print_r($numbers); ?>

In this example, the sort() function is used to sort the array of numbers in ascending order. After sorting, the array is printed to show the sorted order.
