   (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

     Note: The second parameter was added in PHP 4.

   rsort(), usort(), array_multisort(), and uksort().
