sort -- Sort an array


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


$fruits = array ("lemon", "orange", "banana", "apple");
sort ($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
