我正在编写一个模板引擎，我试图在我的模板引擎中添加一个@extends函数来处理一个文件并在运行时在我的页面中运行它：
<?php BakerApp::extends('filename.php',get_defined_vars()); ?>
上面的代码将替换为@extends('filename')和以下代码：
public function extends($BAKER_FILE_NAME,$vars){
$BAKER_FILE_NAME.=baker::$extension;
extract($vars);
eval('?> '.baker::compile(file_get_contents($BAKER_FILE_NAME),0));
}
到目前为止，我的代码工作正常，但是当我在扩展文件中使用@extends时，我的代码输出如下：
Root Page RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>subPage RootPage>...............
虽然这应该如下：
Root Page
RootPage>subPage
rootPage>Subpage>thispage
我的页面是以下代码：
file：page.php
Root Page
@extends('app')
file：app.php
RootPage>subPage
@extends('ext')
file：ext.php
rootPage>Subpage>thispage
我的模板引擎如下：
file：baker2.class.php
<?php
function e($e){
return htmlentities($e);
}
function mprint($array){
echo "<br><pre>";
print_r($array);
echo "<br></pre>";
}
function teletype($char){
mprint(preg_replace('~([\S\s])~', ' $1', $char));exit;
}
function write_in_file($address,$content){
$FileHandle=fopen($address, 'w');
fwrite($FileHandle, $content);
fclose($FileHandle);
}

baker::$extension='.php';

我当前的代码中出现了什么问题？我该如何解决？
