一、练习建立get传值，建立模板list文件。
list.php代码:
<?php
require './public/header.php';
$cate_id=intval(isset($_GET['cate_id'])?$_GET['cate_id']:'');
foreach ($cates as $cate){
if ($cate['cate_id']==$cate_id){
echo '<h2>' . $cate['alias']. '</h2>';
break;
}
}
echo '<ol>';
foreach ($movies as $movie){
if ($movie['cate_id']==$cate_id){
echo '<li>' . $movie['name'] . '</li>';
}
}
echo '</ol>';
require './public/dibu.php';index.php代码：
<?php
require './public/header.php';
foreach ($cates as $cate){
echo '<ol> <h2>' . $cate['alias'] . '</h2>';
foreach ($movies as $movie){
if ($movie['cate_id']==$cate['cate_id']){
echo '<li>' . $movie['name'] . '</li>';
}
}
echo '</ol>';
}
require './public/dibu.php';运行结果：
