Introduction
PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..
<?php function array_union($x, $y) { $aunion= array_merge( array_intersect($x, $y), array_diff($x, $y), array_diff($y, $x) ); return $aunion; } $p = array(1, 2, 3, 4,5); $r = array(2, 3, 4, 5, 6,7,8); print_r(array_union($p, $r)); ?>
