smarty基本用法，循环，判断

require './smarty/Smarty.class.php';

$sm = new Smarty;
$sm->setTemplateDir("./dir");//设置模板路径
$sm->left_delimiter = '<{';//设置左右边界符
$sm->right_delimiter = '}>';
$sm->caching = true;//是否开启缓存
$sm->cache_lifetime = 120;//缓存生命周期
$d = "这个雨季，快结束吧2";
$arr = array('a'=>'小明','b'=>'大欧');

class A{
    public $b='bbb';
}
$obj = new A();


$sm->assign('mytitle',$d);
$sm->assign('obj',$obj);
$sm->assign('t',$arr);
$sm->display('2.html');

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        h1{font-size: 12px;}
    </style>
</head>
<body>
<{Config_load file="xxx.conf"}>
<h1><{$smarty.config.bb}></h1>
<h1><{$mytitle}></h1>
<h1><{$t['a']}></h1>
<h1><{$t.a}></h1>
<h1><{$obj->b}></h1>
<h1><{$smarty.now}></h1>
<h1><{$smarty.get.id}></h1><!--获得$_GET['id'] -->
<h1></h1>
</body>
</html>

循环，判断

<?php
require './smarty/Smarty.class.php';
$sm = new Smarty;
$sm->setTemplateDir("./dir");//设置模板路径
$n = mt_rand(1,9);

$arr = array(
    array('id'=>1,'title'=>'小叶'),
    array('id'=>2,'title'=>'小红'),
    array('id'=>3,'title'=>'小刚')
);

$sm->assign('n',$n);
$sm->assign('arr',$arr);
$sm->display('3.html');

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    {foreach $arr as $k=>$v}
        {$v['id'] + 2}
        {$v['title']}
    {/foreach}
    <h1>
        {if $n == 5}您好啊5
        {else if $n == 4}您好啊4
        {else}您好啊other
        {/if}
    </h1>
</body>
