本文实例讲述了CI框架集成Smarty的方法。分享给大家供大家参考，具体如下：

因为CI自带的模板功能不是很方便，所以大家普遍采用集成Smarty的方式来弥补CI这方面的不足。

本人在网上看了不少CI集成Smarty的教程，包括咱们CI论坛里面的一个精华帖子

http://codeigniter.org.cn/forums/forum.php?mod=viewthread&tid=10345。

自己对比了一下这些教程，我认为下面这个方案是所有里面最优秀的，强烈推荐给大家(当然也是我自己采取的方案)

出处:

http://www.cnmiss.cn/?p=261

原文里面的一些错误，我在本文里面已经做了修正

下面说下我认为它更加优秀的原因，对比下这个方案和我们论坛的方案，你会发现，这个方案多了一点就是它扩展了核心类，

它将Smarty类方法assign和display扩展到Ci的控制器中，所以我们在CI中使用Smarty的时候可以像这样使用：

public function index()
{
    //$this->load->view('welcome_message');
    $data['title'] = '标题';
    $data['num'] = '123456789';
    //$this->cismarty->assign('data',$data); // 也可以
    $this->assign('data',$data);
    $this->assign('tmp','hello');
    //$this->cismarty->display('test.html'); // 也可以
    $this->display('test.html');
}

通过对核心控制器类的简单扩展，大家在CI中使用Smary的时候和直接使用Smarty的用法习惯是一样的，这是一个很大的优点啊。

而且从核心类库的扩展来看，大家也可以看出该文作者对于CI框架的理解是很好的。

根据这篇文章，我不仅成功集成了Smaty，而且也进一步加强了对于CI的理解。

而且该方案将Smarty的配置文件放到了CI框架的config目录下，对于两者，使用都很规范。

最终实现了"CI和Smaty的无缝结合"。

下面开始是具体教程： // 我在原文的基础上做了一些修改，更正了原文的一些错误注意下文中有'//'的地方，是我自己修改过的地方，或是自己又增加的地方。

CI版本：2.1.4 // （本文发布时使用的版本）

Smarty版本：Smarty-2.6.26 // 因为我之前用这个版本，为了照顾自己的使用习惯，这里没有使用最新的Smaty版本，大家理解了扩展原理，可以选择自己想用的Smatry版本。

1、到相应站点下载Smarty的源码包； // 我这里用的是 Smarty-2.6.26

2、将源码包里面的libs文件夹copy到CI的项目目录下面的libraries文件夹下，并重命名为Smarty-2.6.26；//

3、在项目目录的libraries文件夹内新建文件Cismarty.php，里面的内容如下：

<&#63;php
if(!defined('BASEPATH')) EXIT('No direct script asscess allowed');
require_once( APPPATH . 'libraries/Smarty-2.6.26/libs/Smarty.class.php' );
class Cismarty extends Smarty {
  protected $ci;
  public function __construct(){
    $this->ci = & get_instance();
    $this->ci->load->config('smarty');//加载smarty的配置文件
    //获取相关的配置项
    $this->template_dir  = $this->ci->config->item('template_dir');
    $this->complie_dir  = $this->ci->config->item('compile_dir');
    $this->cache_dir   = $this->ci->config->item('cache_dir');
    $this->config_dir   = $this->ci->config->item('config_dir');
    $this->template_ext  = $this->ci->config->item('template_ext');
    $this->caching    = $this->ci->config->item('caching');
    $this->cache_lifetime = $this->ci->config->item('lefttime');
  }
}

4、在项目目录的config文件夹内新建文件smarty.php文件,里面的内容如下：

<&#63;php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$config['theme']    = 'default';
$config['template_dir'] = APPPATH . 'views';
$config['compile_dir'] = FCPATH . 'templates_c';
$config['cache_dir']  = FCPATH . 'cache';
$config['config_dir']  = FCPATH . 'configs';
$config['template_ext'] = '.html';
$config['caching']   = false;
$config['lefttime']   = 60;

5、在入口文件所在目录新建文件夹templates_c、cache、configs；

6、在项目目录下面的config目录中找到autoload.php文件
修改这项

$autoload['libraries'] = array('Cismarty');
//目的是：让系统运行时，自动加载，不用人为的在控制器中手动加载

7、在项目目录的core文件夹中新建文件MY_Controller.php 内容如下： // 扩展核心控制类

<&#63;php if (!defined('BASEPATH')) exit('No direct access allowed.');
class MY_Controller extends CI_Controller { // 原文这里写错
  public function __construct() {
    parent::__construct();
  }
  public function assign($key,$val) {
    $this->cismarty->assign($key,$val);
  }
  public function display($html) {
    $this->cismarty->display($html);
  }
}

配置完毕

使用方法实例：

在控制器中如：

<&#63;php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends MY_Controller { // 原文这里写错
  public function index()
  {
    //$this->load->view('welcome_message');
    $data['title'] = '标题';
    $data['num'] = '123456789';
    //$this->cismarty->assign('data',$data); // 亦可
    $this->assign('data',$data);
    $this->assign('tmp','hello');
    //$this->cismarty->display('test.html'); // 亦可
    $this->display('test.html');
  }
}

然后再视图中：试图文件夹位于项目目录的views之下：

新建文件test.html

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>{ $test.title}</title> //（ 原文是 <title>{$test['title']}</title>，是错误的写法，也有可能是Smarty版本的原因）
<style type="text/css">
</style>
</head>
<body>
{$test.num|md5} // 原文这里也写错了
<br>
{$tmp}
</body>
</html>

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
