How to use PHP sort() Function In PHP
We will use the built-in sort() function to sort the input array into ascending to descending order. It sorts the actual array and hence changes are reflected in the original array itself.
Syntax
sort(array &$array, int $sort_flags = SORT_REGULAR): bool
Example: This example uses the built-in sort() function to sort the input array into the correct order.
PHP
<?php function sortArray($arr) { sort($arr); return $arr; } $arr1 = [3, 1, 4, 5, 2, 8, 6, 10, 7]; $arr2 = [3, 1, 4, 5, 2, 0, 10]; $result1 = sortArray($arr1); $result2 = sortArray($arr2); echo "Sorted Array is: [" . implode(", ", $result1) . "]\n"; echo "Sorted Array is: [" . implode(", ", $result2) . "]\n"; ?> |
Output
Sorted Array is: [1, 2, 3, 4, 5, 6, 7, 8, 10] Sorted Array is: [0, 1, 2, 3, 4, 5, 10]
How to Sort an Array containing 1 to n values in PHP ?
In this article, we will see how to sort an array that contains 1 to n values in PHP. There are various approaches through which we can sort an array with custom values. Below is an example for a better understanding of the problem statement.
Example:
Input: arr = [3, 1, 4, 5, 2, 8, 9, 5] Output: Sorted Array is: [1, 2, 3, 4, 5, 8, 9] Input: arr = [3, 1, 4, 5, 2, 0, 10] Output: Sorted Array is: [0, 1, 2, 3, 4, 5, 10]
