Blocks

I created block: "simplehtml", in my block:

1. block_simplehtml.php
   <?php
   
   class block_simplehtml extends block_base {
   ...
       public function get_content() {
       ....
            $data = ...;
             $this->content = WHAT_FUNCTION_CALL( 'view', $data);  //render html from view_file_php
       ....
       }
   ...
   }
   
   ?>
2. view.php
   
      <div>
          //Write your code here      
        <?php $data....blabla?>
       </div>

Please give me some suggestion what function I can do it. (WHAT_FUNCTION_CALL????)
