自制php模板引擎第二版

这是继上次的《超简单实用的php 模板引擎》改进后第二个版本，加入了子模版的语法；允许模板嵌套调用；如我所愿，所有代码在100行内完成，虽然代码相当简陋，功能和那些强大的模板引擎没法比。不过，小巧精致，同时也相当实用，为小系统的快速开发提供帮助。

子模版语法：

#include ‘header’

代码修改的部分，我帖了出来，其余的请到之前写的文章中查阅^_^

 private function parse($str){
        $retarr =  $this->token($str);
        foreach($retarr as $key=>$v){
            $tokenname = @token_name($v[1][0]);
            switch($tokenname){
                case 'T_VARIABLE':
                   $str = str_replace("#$key","<?php echo {$v[1][1]} ?>",$str);
                   break;
                case 'T_INCLUDE':
                    for($i=1;$i<count($v);$i++){
                        if( @token_name($v[$i][0]) == 'T_CONSTANT_ENCAPSED_STRING'){
                            $search = array("'","\"");
                            $subtemp = $this->template_path."/".str_replace($search,"",$v[$i][1]);
                            if(file_exists($subtemp)){
                                $substr = file_get_contents($subtemp);
                                $replacestr = $this->parse($substr);
                            }
                            else if(file_exists($subtemp=$subtemp.$this->template_surfix)) {
                                $substr = file_get_contents($subtemp);
                                $replacestr = $this->parse($substr);
                            }
                            else{
                               $replacestr = "";
                            }
                            $str = preg_replace("/#include.*{$v[$i][1]}/i",$replacestr,$str);
                        }
                    }
                    break;
                default:
                   $str = str_replace("#".$key,"<?php $key ?>",$str);
            }
        }
        return ($str);
      }
