Smarty is often used in projects, but the simple assgin display foreach if else and other methods are always used. I watched smarty again when I had some free time. Simply record what is useful.
<br> <span>smarty 系统保留变量 </span><span>$smarty</span>.<span>get #使用方法 $smarty.get.id 下面的一次类推 </span><span>$smarty</span>.<span>post </span><span>$smarty</span>.<span>session </span><span>$smarty</span>.<span>cookie </span><span>$smarty</span>.server<br> smarty模板中使用PHP中定义的常量<br> php 文件中定义 define('HIEGHT', 8846);<br> 模板文件中使用 $smarty.const.HIEGHT<br> smarty读取配置文件中的变量<br> 1 $smarty->config_dir = "./conf"; #设置配置文件的路径<br> 2 配置文件的书写规则 1)配置文件以.conf 结尾 2)配置文件内的书写规则 key1=val1 key1=val1 <br> 3 使用:在模板文件的头部 {config_load file='site.conf'} <br> 4 {$smarty.config.site} 即可获取 // {#site#}也可以读取<br> smarty缓存设置<br> $smarty->caching = true; #开启缓存 缓存页面<br> $smarty->cache_lifetime = 3600; #缓存的时间<br> $smarty->cache_dir = './cache'; #存放换文件的目录 <br> $smarty->isCached('news.html') 可以判断是否生成了缓存文件 #smarty3里面这么判断<br> <br> #一个页面生成多个缓存文件 例子:一个商品详情的页面 根据商品的ID 展现不同的内容 <br> $id = empty($_GET['id]) ? 1 : $_GET['id'];<br> $good_name = 'good_name_' . $id;<br> $smarty->assign('good_name',$good_name);<br> $smarty->display('tpm.html',$id); # 这样就会根据id生成不同的页面 。 <br> 注意: 实际的项目中 这个ID 应该是根据参数算出来的。例如根据page,category等参数计算出来。之前公司的一个项目用到了smarty的缓存,这个id的值就是根据page category md5以后得到的。 ecshop中也是这么做的 不过不是MD5。<br> #清除缓存<br> $smarty->clearCache('tmp_name')<br> $smarty->clearAllCache() <br> <br> #设置局部不缓存的方法<br> 1 在标签中 {$time|date_format:"%Y-%M-%D %H:%M:%S" nocache}<br> 2 {nocache}{/nocache} 控制局部不缓存<br> 3 php赋值的时候控制不缓存 assign 的第三个参数 设置为true <br> 4 smarty中的一个insert方法 不细说 感觉没啥用 (囧)
######个人感觉smarty的缓存意义不太大。因为完全可以用redis MEMCHACHE 代替。当然存在即合理 哈哈 <br> <br> #变量调节器 :简单说 修改变量的展示形式的功能 例如:
{$time|date_format:"%Y-%M-%D %H:%M:%S" nocache}<br> #自己也可以写变量调节器 参照plugin里面的文件写就可以了 ###感觉有用。我们的项目中用到了。具体的使用,回头补上。<br>
Smarty acquisition:
1 download: http://www.smarty.net/download
2 Get it through composer: Composer is a very good thing.

The above is an introduction to smarty, including some aspects. I hope it will be helpful to friends who are interested in PHP tutorials.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
