哈哈，我的小框架早就出来了。虽然根本称不上是框架。

总的来说就是变量替换~~~~麻烦...

作者: xyiyo 发布时间: 2008-05-05

本人也觉得模板引擎没必要一定用!额外开销很大~而且功能有所限制!所以把模板引擎换成模板类了~

复制PHP内容到剪贴板

PHP代码:

<?php
/**
* Template
*
* @package
* @author xusong Lie
* @copyright 2008
* @version 1.0
* @access public
*/
class Template {
    var $tpl_vars;
    var $templatePath;

    function Template() {
        $this->tpl_vars = array();
        $this->templatePath = 'templates/';
    }

    function setTemplatePath($path) {
        if(is_dir($path))
            $this->templatePath = $path;
        else
            die($path.' is not a right path.');
    }

    function assign($key,$val=null) {
        if(!isset($key)) return false;
        if(is_array($key) && !isset($val)) {
            if(sizeof($this->tpl_vars) > 0) {
                $this->tpl_vars = array_merge($this->tpl_vars,$key);
            } else {
                $this->tpl_vars = $key;
            }
        } else {
            $this->tpl_vars[$key] = $val;
        }
        return true;
    }//end of assign()

    function display($filename) {
        $tpl_file = $this->templatePath.$filename;
        if(!file_exists($tpl_file)) die('Template file is not exists.');
        if(sizeof($this->tpl_vars) > 0) {
            foreach($this->tpl_vars as $var => $value) {
                $$var = $value;
            }
        }
        ob_start();
        include_once($tpl_file);
        $content = ob_get_contents();
        ob_end_clean();

        echo $content;
        return true;
    }//end of display()
}

?>

我觉得这个类更好用~~~谢谢大家支持!

所谓模板，核心就是读模板文件内容到一个字符串，然后替换定义的字符最后输出
