一、模板语法规则
1、变量表示
{$name} 被解析成 <?=$name?>，表示显示变量$name的值，其中的“name”由英文字母、数字和下划线组成首字母必须是英文字母或者下划线。
2、常量表示
{name}被解析成<?=name?>，表示显示常量name的值，其中的“name”由英文字母、数字和下划线组成首字母必须是英文字母或者下划线。
3、条件判断
{if *} * {else} * {else} * {/if} 或者 {if *} * {/if}，其中{if *}中的*就是此判断语句的条件表达式，符合php的表达式。
{if $userid} {$username}{else} {$noname}{/if}
4、循环
{loop $a $b} * {/loop} 或者 {loop $a $b $c} * {/loop} ，{loop $a $b} * {/loop}
被解析成 <? if(is_array($a)) foreach($a AS $b) { ?> * <? } ?>
而 {loop $a $b $c} * {/loop} 则被解析成 <? if(is_array($a)) foreach($a AS $b=>$c) { ?> * <? } ?>
5.模板包含
{template 'module name','file name'}例如: {template 'phpcms','header'}表示包含模板目录,phpcms目录下header.html文件
建议 if 和 loop 语法应该写在html注释符之间，这样可以避免在编辑工具中难看，例如：
这样写 if
<!--{if $a>$b}--> <!--{else}--> <!--{/if}-->
这样写 loop
<!--{loop $arr $key $val}--> <!--{/loop}-->
如果您不习惯这套语法，也可以直接在模板中书写php代码，例如<?php echo 'Hello World!';?>
二、模板制作常用变量
常用的系统变量
打开文件 ./include/common.inc.php
IP //取得ip
TIME //取得时间戳，格式（1229393941 ）可以通过date 函数格式化一个本地时间／日期，请参考php手册
URL //取得当前浏览的url地址
SITE_URL //网站的url地址
//以上是系统常量，直接调用，如（）
