PHP 模板smarty练习
一.练习环境

smarty_inc为smarty lib库
smarty_inc.php导入库文件

<?phpinclude_once ("smarty_inc/Smarty.class.php");$smarty = new Smarty(); //实例化$smarty->config_dir="Smarty/Config_File.class.php";$smarty->caching=false; //缓存$smarty->template_dir = "./templates"; //模板文件$smarty->compile_dir = "./templates_c"; // 设定编译文件的存储路径//$smarty->cache_dir = "./smarty_cache";$smarty->left_delimiter = "{";$smarty->right_delimiter = "}";?>

二.smarty变量练习
$smarty->assign 设置传输变量
$smarty->display 加载模板
index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$str = 'this is my home!';$smarty->assign('str',$str);$smarty->display("index.html");?>

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body> {$str}</body></html>

访问localhost/smarty/index.php 直接转到index.html
this is my home!

三.smarty数组练习
index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$students = ['sunqing','liuyao','yuxx','王舞'];$smarty->assign('name',$students);$smarty->display("index.html");

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body> {section name=stu loop=$name} {$name[stu]} {sectionelse} 无内容 {/section}</body></html>

四.smarty二维数组练习
index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$students[] = ['stu_name'=>'sunqiang'];$students[] = ['stu_name'=>'liuyao'];$students[] = ['stu_name'=>'yuxx'];$smarty->assign('name',$students);$smarty->display("index.html");

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body> {section name=stu loop=$name} {$name[stu].stu_name} {sectionelse} 无内容 {/section}</body></html>

五.smarty标量操作符练习
index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$str = 'this is my home!';$smarty->assign('str',$str);$smarty->assign('time',time());$smarty->assign('score',123.456);$smarty->display("index.html");

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body>原始字符：{$str} <hr>首字母大写：{$str|capitalize} 计算字符数：{$str|count_characters} 连接内容：{$str|cat:' i love study php'} 段落数：{$str|count_paragraphs} 计算句数：{$str|count_sentences} 计算单词数:{$str|count_words} 日期显示:{$time|date_format:'%Y-%m-%d %H:%M:%S'} | {$smarty.now|date_format:'%Y-%m-%d %H:%M:%S'} | {$smarty.now} 默认显示值:{$str1|default:'no content'} 转码:{$str|escape:url} | {$str|escape:html} 缩进：{$str|indent:5:'.'} | {$str|indent:5:' '} 大写：{$str|upper} 小写：{$str|lower} 替换：{$str|replace:'my':'your'} | {$str|replace:'my':'**'} 字符串格式化：{$score|string_format:'%.2f'} | {$score|string_format:'%d'} 去空格：{$str|strip:''} | {$str|strip:'_'} 去html标签：{$str|strip_tags} 截取：{$str|truncate:10:'...'} 行宽约束：{$str|wordwrap:10:' '}</body></html>

六.smarty内置函数练习

1.有键值数组
index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$arr_str = ['teacher1'=>'sq','teacher2'=>'ly','teacher3'=>'yxx'];$smarty->assign('teacher_name',$arr_str);$smarty->display("index.html");

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body> {foreach from=$teacher_name item=name key=teach} 数组内容：{$teach} - {$name} {/foreach}</body></html>

2.无键值数组

index.php

<?phpinclude ("smarty_inc.php");error_reporting(7);//不显示警告报错，255列出所有提示，0关闭所有提示$arr_str = ['sq','ly','yxx'];$smarty->assign('teacher_name',$arr_str);$smarty->display("index.html");

index.html

index.php

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body> {foreach from=$teacher_name item=name} 数组内容：{$name} {/foreach}</body></html>

3.if条件语句
index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body>条件语句： {if name==''} 没有设置内容 {else} 有设置内容 {/if}</body></html>

因为index.php没有设置这个变量，所有显示没有设置内容

4.include的使用
在模板下创建一个拼接文件head.html

index.html

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>smarty test</title></head><body>{include file='head.html'}条件语句： {if name==''} 没有设置内容 {else} 有设置内容 {/if}</body></html>

注：
{include file=‘d:\www\index2.php’} 可以是别的目录下的引入文件
{include file='head.html' title=‘menu’}引入head.html,将title的值传给head.html的中的变量title

5.literal的使用
literal数据将被当作文本处理，此时模板将忽略其内部的所有字符信息，该特性用于显示有可能包含大括号等字符信息的javascript脚本,因为在模板设置中php的边界设定为大括号，防止冲突。

{literal} <script language=javascript> ...... </script>{/literal}

6.Strip的使用
strip标记中数据的首尾空格和回车，这样可以保证模板容易理解且不用担心多余的空格导致问题，使用会做整行的处理，但内容不变，同时节省了流量，还可以保护代码。
使用时在html代码头和尾
{strip}
<html>
</html>
{/strip}
