echo php code by php; is that possible -

i want echo out php code educational purposes. possible? @ same time need code php code executed.

adding html special-chars this:

$this->art = file_get_contents("$this->mainpage/$this->dir/$this->article"); 

it becomes:

$this->art = htmlspecialchars( file_get_contents("$this->mainpage/$this->dir/$this->artikel")); 

but still not output code php interpreter seems hold of code , directly interprets it. htmlspecialchars () has got effect on html code, see article in brackets.

i tried using .html files instead of .php files. php interprets if rename .jpeg.

i'm @ wit's end. grateful answer. thanking in advance.

i dont understand, why 1 consider doing way, pretty easy. file_get_content not run code, while include will.

define('ds', directory_separator);  // logic starts here public function main() {     echo '<hr><pre>' . $this->educlude($this->mainpage . ds. $this->dir . ds . $this->artikle) . '</pre>'; }  public function educlude($file) {     include $file;     return htmlspecialchars(file_get_contents($file)); } 

this echo

hello world

---

<?php echo 'hello world';

for given file:

<?php echo 'hello world';
