php smarty框架的初步使用和注意事项
1.什么是模板引擎
两个部分比较关心
1.1就是GUI(视图,界面) --HTML CSS JAVASCRIPTE
1.2是业务逻辑(php编码) --PHP MYSQL
模板引擎是使用php开发的一个项目
2.Smarty
2.1安装
1.解压,只用到libs目录,需要使用Smarty.class.php和插件文件夹
2.创建文件夹:templates和template_c文件夹(默认文件夹名)
3.创建php文件(见例子)
include "./libs/Smarty.class.php";
设置替换内容,设置显示模板
4.访问
2.2Smarty初始化
1.初始化可以在Smarty.class.php中修改制定值
2.在php页面调用的时候初始化
//解决问题:Warning: strftime() [function.strftime]:
date_default_timezone_set("Asia/Shanghai");
include "./libs/Smarty.class.php";
$tpl = new Smarty();
//smarty初始化
$tpl->template_dir="./templates/";
$tpl->compile_dir="./template_c/";
$tpl->left_delimiter="";
2.3Smarty使用注意事项
1.查找资源(css/js/image)
资源文件放在访问的php页面对应的资源位置(因为访问时模板是被包含在php文件当中的)
2.所有的display模板时(还是include),都要指定Smarty模板中的指定的基路径
3.模板目录之外的php引用smarty文件时,将Smarty的初始文件换成绝对路径
示例代码:
init.smarty.php
<?php define(ROOT, ""); //解决问题:Warning: strftime() [function.strftime]: date_default_timezone_set("Asia/Shanghai"); include ROOT."./libs/Smarty.class.php"; $tpl = new Smarty(); //smarty初始化 $tpl->template_dir=ROOT."./templates/"; $tpl->compile_dir=ROOT."./template_c/"; $tpl->left_delimiter="<!--{"; $tpl->right_delimiter="}-->"; ?>
mysmarty.php
<?php //如果文件加载失败require会停止继续解析php;而include则会继续向下执行 require 'init.smarty.php'; //程序简单方式 $title="这是一个文字标题,从数据库中获取"; $content = "这是内容"; $tpl->assign("title",$title); $tpl->assign("content",$content); //模板文件名可以随便定义:比如:mysmarty.tpl只有内容是html就可以了 $tpl->display("mysmarty.html"); ?>
mysmarty.html
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title><!--{$title}--></title> <!--{$content}-->

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

MinGW - Minimalist GNU for Windows
This project is in the process of being migrated to osdn.net/projects/mingw, you can continue to follow us there. MinGW: A native Windows port of the GNU Compiler Collection (GCC), freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All MinGW software can run on 64-bit Windows platforms.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
