介绍PHP5的给类型函数应用

<?php
// Declare two arrays:
$first = array('e', 'h', 'r', 'j', 'b');
$last = array('w', 'e', 'c');

// Combine them using PHPs + operator
$plus_union = $last + $first;

// Echo this out:  w e c j b
echo '<p>';
foreach ($plus_union as $v) { echo "{$v} "; } 
echo "</p>\n";

// Combine them using merge & unique, getting a true union
$union = array_unique(array_merge($first, $last));

// Echo this out:  e h r j b w c 
echo '<p>';
foreach ($union as $v) { echo "{$v} "; } 
echo "</p>\n";
?>
