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
