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');

// Determine the intersection of these sets
$intersection = array_intersect($last, $first);

// Echo this out:  e
echo '<p>';
foreach ($intersection as $v) { echo "{$v} "; } 
echo "</p>\n";
?>
