Using PHP as a template engine

Question

I am not going to argue about the choice of a template engine against only PHP. I choose not to use a template engine, like Smarty, because I would like to learn how to prop

Answer 1

 function returnView($filename,$variables){
    ob_start();
        $htmlfile = file_get_contents($filename);  
        foreach($variables as $key=>$value){
          $htmlfile = str_replace("#".$key."#", $value, $htmlfile);
        }              
        echo $htmlfile;
    return ob_get_clean(); 
 } 

//htmlfile





//usage

echo returnView('file.html',array('title'=>'hello world!');

im my framework i have function that loads view, and then outs it in layout:

 public function returnView(){
    ob_start();
    $this->loader();
    $this->template->show($this->controller,$this->action);
    return ob_get_clean(); 
 }

Layout looks like this:

 
    
        
    
    
        layout('content'); ?>
