参考了smarty的官方文档，不过是翻译了部分，也加了点注释，个人感觉是比较有用的。欢迎交流。
1、循环一个简单的一维数组：
Example 7-30. Looping a simple array with {section}
<?php
$data = array(1000,1001,1002);
$smarty->assign(‘custid’,$data);
?>
//customer和下面的foo可以随便命名，作用其实仅仅是一个index下标，用来引用数组中的元素
{section name=customer loop=$custid}
id: {$custid[customer]}<br />
{/section}
<hr />
{section name=foo loop=$custid step=-1}
{$custid[foo]}<br />
{/section}
//输出
id: 1000<br />
id: 1001<br />
id: 1002<br />
<hr />
id: 1002<br />
id: 1001<br />
id: 1000<br />
2、不用assign数组直接在smarty中循环：
Example 7-31. {section} without an assigned array
//特别地设置了start,step属性用来控制循环
//$smarty.section.section的名字.index是一个特殊变量，用来显示当前循环的位置
{section name=foo start=10 loop=20 step=2}
{$smarty.section.foo.index}
{/section}
<hr />
{section name=bar loop=21 max=6 step=-2}
{$smarty.section.bar.index}
{/section}
//输出：
10 12 14 16 18
<hr />
20 18 16 14 12 10
3、section的name的值是随你定的
Example 7-32. Naming a {section}
{section name=anything loop=$myArray}
{$myArray[anything].foo}
{$name[anything]} //这种用法目前还没怎么用过，也不太清楚
{$address[anything].bar} //这种也是
{/section}
4、遍历一个关联数组，嵌套的数组
<?php
$data = array(
array(‘name’ => ‘John Smith’, ‘home’ => ‘555-555-5555’,
‘cell’ => ‘666-555-5555′, ’email’ => ‘john@myexample.com’),
array(‘name’ => ‘Jack Jones’, ‘home’ => ‘777-555-5555’,
‘cell’ => ‘888-555-5555′, ’email’ => ‘jack@myexample.com’),
array(‘name’ => ‘Jane Munson’, ‘home’ => ‘000-555-5555’,
‘cell’ => ‘123456’, ’email’ => ‘jane@myexample.com’)
);
$smarty->assign(‘contacts’,$data);
?>
//section不用嵌套，因为只有一个数组，数组内部用$contacts[customer]得到
//每个数组，再用.键名来得到键值
{section name=customer loop=$contacts}
<p>
name: {$contacts[customer].name}<br />
home: {$contacts[customer].home}<br />
cell: {$contacts[customer].cell}<br />
e-mail: {$contacts[customer].email}
</p>
{/section}
The above example will output:
<p>
name: John Smith<br />
home: 555-555-5555<br />
cell: 666-555-5555<br />
e-mail: john@myexample.com
</p>
<p>
name: Jack Jones<br />
home phone: 777-555-5555<br />
cell phone: 888-555-5555<br />
e-mail: jack@myexample.com
</p>
<p>
name: Jane Munson<br />
home phone: 000-555-5555<br />
cell phone: 123456<br />
e-mail: jane@myexample.com
</p>
5、从数据库查询记录显示，实际上是显示二维数组，其实同上例一样
<?php
$sql = ‘select id, name, home, cell, email from contacts ‘
.”where name like ‘$foo%’ “;
$smarty->assign(‘contacts’, $db->getAll($sql));
?>
//结果：
<table>
<tr><th> </th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
{section name=co loop=$contacts} //第一维
<tr>
<td><a href=”view.php?id={$contacts[co].id}”>view<a></td> //第二维用.号来引用
<td>{$contacts[co].name}</td>
<td>{$contacts[co].home}</td>
<td>{$contacts[co].cell}</td>
<td>{$contacts[co].email}</td>
<tr>
{sectionelse}
<tr><td colspan=”5″>No items found</td></tr>
{/section}
</table>
6、嵌套的section
<?php
$id = array(1001,1002,1003);
$smarty->assign(‘custid’,$id);
$fullnames = array(‘John Smith’,’Jack Jones’,’Jane Munson’);
$smarty->assign(‘name’,$fullnames);
$addr = array(‘253 N 45th’, ‘417 Mulberry ln’, ‘5605 apple st’);
$smarty->assign(‘address’,$addr);
$types = array(
array( ‘home phone’, ‘cell phone’, ‘e-mail’),
array( ‘home phone’, ‘web’),
array( ‘cell phone’)
);
$smarty->assign(‘contact_type’, $types);
$info = array(
array(‘555-555-5555’, ‘666-555-5555’, ‘john@myexample.com’),
array( ‘123-456-4’, ‘www.example.com’),
array( ‘0457878’)
);
$smarty->assign(‘contact_info’, $info);
?>
{section name=customer loop=$custid}
<hr>
id: {$custid[customer]}<br />
name: {$name[customer]}<br />
address: {$address[customer]}<br />
{section name=contact loop=$contact_type[customer]}
{$contact_type[customer][contact]}: {$contact_info[customer][contact]}<br />
{/section}
{/section}
The above example will output:
<hr>
id: 1000<br />
name: John Smith<br />
address: 253 N 45th<br />
home phone: 555-555-5555<br />
cell phone: 666-555-5555<br />
e-mail: john@myexample.com<br />
<hr>
id: 1001<br />
name: Jack Jones<br />
address: 417 Mulberry ln<br />
home phone: 123-456-4<br />
web: www.example.com<br />
<hr>
id: 1002<br />
name: Jane Munson<br />
address: 5605 apple st<br />
cell phone: 0457878<br />
