下面为大家带来一篇老生常谈ThinkPHP中的行为扩展和插件(推荐)。小挺不错的,现在就分享给大家,也给大家做个参考。

原理分析

将标签与类之间的对应关系(如'app_init'=>array('Common\Behavior\InitHook')),通过Hook类中import或add方法,加载到Hook类中静态变量$tags中。当执行Hook中静态方法listen或者exec方法的时候(listen方法中调用了exec),实例化标签对应的类,调用相应的方法(如果是插件,调用传递的方法,如果是行为,调用run方法)。

Hook中exec方法定义如下:

static public function exec($name, $tag,&$params=NULL) {
    if(false === strpos($name,'\\')) {
      // 插件(多个入口)
      $class  = "Addons\\{$name}\\{$name}Addon";
    }else{
      // 行为扩展(只有一个run入口方法)
      $class  = $name.'Behavior';
      $tag  =  'run';
    }
    $addon  = new $class();
    return $addon->$tag($params);
  }

ThinkPHP中的行为

加载标签与类之间的对应关系

// 加载模式行为定义

if(isset($mode['tags'])) {
  Hook::import(is_array($mode['tags'])?$mode['tags']:include $mode['tags']);
}
// 加载应用行为定义
if(is_file(CONF_PATH.'tags.php'))
  // 允许应用增加开发模式配置定义
  Hook::import(include CONF_PATH.'tags.php');

模式行为对应关系

在ThinkPHP/Mode/common.php中tags标签中定义

'tags' => array(
    'app_begin'   => array(
      'Behavior\ReadHtmlCache', // 读取静态缓存
    ),
    'app_end'    => array(
      'Behavior\ShowPageTrace', // 页面Trace显示
    ),
    'view_parse'  => array(
      'Behavior\ParseTemplate', // 模板解析 支持PHP、内置模板引擎和第三方模板引擎
    ),
    'template_filter'=> array(
      'Behavior\ContentReplace', // 模板输出替换
    ),
    'view_filter'  => array(
      'Behavior\WriteHtmlCache', // 写入静态缓存
    ),
  )

应用行为对应关系

在Application/Common/Conf/tags.php中定义

调用相应的行为

如Hook::listen('app_begin')相当于调用Behavior\ReadHtmlCache中的run方法。找到该类,可以查看其对应的run方法如下

自定义行为

1.在Application/Common/Conf/tags.php中添加对应关系

'dqs_behavior'=>array('Common\Behavior\Dqs')

将对应关系添加到tags.php,程序会自动将其加载到Hook的$tags变量中,当然也可通过使用Hook中的add方法手动加载。

2.定义Common\Behavior\DqsBehavior类

<?php
namespace Common\Behavior;
use Think\Behavior;

defined(&#39;THINK_PATH&#39;) or exit();

class DqsBehavior extends Behavior {

  public function run(&$content){
    echo &#39;<pre class="brush:php;toolbar:false">&#39;;
    print_r(&#39;调用了行为Dqs&#39;);
    echo &#39;
';   } }

其中Behavior 类为ThinkPHP自带的抽象类

3.调用行为

效果如下图

自定义插件

1.定义插件文件

通过查看Hook文件中插件类实例化方式($class = "Addons\\{$name}\\{$name}Addon";),可以得知,如果想定义一个名为Dqs的插件,应该在Addons/Dqs目录下定义DqsAddon.class.php文件。程序如下:

<?php
namespace Addons\Dqs;
class DqsAddon{  
  public $info = array(
      &#39;name&#39;=>&#39;Editor&#39;,
      &#39;title&#39;=>&#39;dqs测试插件&#39;,
      &#39;description&#39;=>&#39;主要用于输出&#39;,
      &#39;status&#39;=>1,
      &#39;author&#39;=>&#39;lidequan&#39;,
      &#39;version&#39;=>&#39;0.1&#39;
  );
  public function dqsTrace($pa){
    echo &#39;<pre class="brush:php;toolbar:false">&#39;;
    print_r($pa);
    echo &#39;
';   } }

2.注册插件

所谓的注册插件,就是将插件的标签与类之间的对应关系,添加到Hook类中静态变量$tags中。对应行为来说,标识符仅仅是一个标识符,可以定义任意的标识符,但是对应插件来说,标识符不能随意定义,因为插件的标识符代表的是插件的方法名。所以上面的插件注册代码如下

\Think\Hook::add(&#39;dqsTrace&#39;,array(&#39;Dqs&#39;));

3.调用插件

$params=array(&#39;name&#39;=>&#39;dqs&#39;);
\Think\Hook::listen(&#39;dqsTrace&#39;,$params);

效果如下

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
