$code = strtoupper(substr(md5(time()),0,5));

echo '<div>'.$code.'</div>';
 echo '<form method="post" action="some_php_file.php">
<div>
insert the security code from above <input type="text" name="captcha_code" value=""/><input type="hidden" name="captcha_code_check" value="'.$code.'"/>
</div>
</form>
'; 

some_php_file.php

if($_POST['captcha_code']!=$_POST['captcha_code_check']) $error = 'Wrong security code';
if(!empty($error)) echo $error; 

but this type of captcha doesnt make any sense, because its very easy for bots to read the captcha text.

May he mean no $_SESSION[]

what for?
there are many different ways to create captcha, session is not the best solution for captche on a mobile site.

he means if i click submit nothing is stoping me to click refresh and that code is useless...
If you want to do text you can do something like: whats 3+4 ?
Just store in an array the question =>answer and random select one to be displayed and put the answer in session just like image captcha
