sort

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
