php之Smarty3 模块的安装调优
Smarty模板的使用时为了使用户界面和业务数据分离开
安装Smarty,官方下载网址:http://www.smarty.net/download.php
解压后只要将文件夹里“libs”文件夹拷贝到根目录下
而libs中也只要用到 Smarty.class.php 这个类php
在根目录下建立要用的文件
其中 tpls : 模板的目录,coms : 生成的目录,这两在开发是这个目录不要放在web服务器的根目录下
tpls目录下创一个demo.html,这是一个表现层界面
<title></title> <style> body {color:red;} </style> <br> <br> <br> <img src="/static/imghwm/default1.png" data-src="img.gif" class="lazy" alt="php之Smarty3 模块的装配调优" > <script> if(true){ alert(new Date()); } </script>
在 init.inc.php 中用于存放php中初始化的代码
同样要设置模板文件存放目录和编译目录,并且为了防止与空格发生冲突,我们修改定界符
这里要强调的是指定输出的固定目录,这样不止能在根目录下调用,也能在外目录下调用
<?php //输出指定的固定目录,并将"\"转成"/",做到跨目录 define("ROOT",str_replace("\\","/",dirname(__FILE__)).'/'); require ROOT."/libs/Smarty.class.php"; //创建模板引擎对象 $smarty = new Smarty(); //smarty3设置存放目录 $smarty->setTemplateDir(ROOT."/tpls") ->setCompileDir(ROOT."/coms");//指定编译目录 //修改定界符,防止与空格发生冲突 $smarty->auto_literal=false; //默认true,false不与空格冲突 $smarty->left_delimiter="right_delimiter="}>";
demo.php 是主要的文件,主要是用 assign() 方法将变量植入模板中,再用 display() 方法将网页输出
<?php include "init.inc.php"; $smarty->assign("title","11111111"); $smarty->assign("content","2222222222"); $smarty->display("demo.html");
基本的Smarty用法就像上面那样,不过这只是Smarty一小部分,Smarty是功能非常强大的模板

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
