Often, we want to sort the elemments of an array. The program below uses the built-in PHP sorting function to sort and reverse sort an array of elements.
<?php // Create an associative array $saTribesOfIsrael = array("Reuben", "Simeon", "Levi", "Judah", "Issachar", "Zebulun", "Dan", "Naphtali", "Gad", "Asher", "Joseph", "Benjamin"); echo "<h1>Array Sorting Methods:</h1>"; // Use a foreach loop to print each key with its value echo "<h3>Original Order:</h3>"; foreach ($saTribesOfIsrael as $sKey => $sValue) { echo "{$sKey} => {$sValue}<br />"; } echo "<br />"; sort($saTribesOfIsrael); // Use a foreach loop to print each key with its value echo "<h3>Alphabetical Sort Order:</h3>"; foreach ($saTribesOfIsrael as $sKey => $sValue) { echo "{$sKey} => {$sValue}<br />"; } echo "<br />"; rsort($saTribesOfIsrael); // Use a foreach loop to print each key with its value echo "<h3>Reverse Alphabetical Sort Order:</h3>"; foreach ($saTribesOfIsrael as $sKey => $sValue) { echo "{$sKey} => {$sValue}<br />"; } echo "<br />"; ?>
