# sort

(PHP 3, PHP 4 )

sort -- Sort an array

## Description

void sort ( array array [, int sort_flags])

This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.

Example 1. sort() example

    <?php

    $fruits = array ("lemon", "orange", "banana", "apple");
    sort ($fruits);
    reset ($fruits);
    while (list ($key, $val) = each ($fruits)) {
        echo "fruits[".$key."] = ".$val."\n";
    }

    ?>

This example would display:

    fruits[0] = apple
    fruits[1] = banana
    fruits[2] = lemon
    fruits[3] = orange

The fruits have been sorted in alphabetical order.

The optional second parameter `sort_flags` may be used to modify the sorting behavior using these values:

Sorting type flags:

- SORT_REGULAR - compare items normally

- SORT_NUMERIC - compare items numerically

- SORT_STRING - compare items as strings

See also arsort(), asort(), ksort(), natsort(), natcasesort(), rsort(), usort(), array_multisort(), and uksort().

> Note: The second parameter was added in PHP 4.
