codeigniter captcha Allowed memory

php.ini

Try changing these:

memory_limit=256M

For Forms / upload/download:
These two settings should be set to the same amount.

post_max_size=16M
and
upload_max_filesize=16M

Ther'isnt a problem of memory , this appear because ther's something  as a loop wich save image until the memory_limit are reached, the problem is why ?

show us the code.

the code is on the first post :

Code:

// This function generates CAPTCHA image and store in "image folder".
     public function captcha_setting(){
       
      $this->load->helper('captcha');

       
       $vals = array(
           'img_path' => './captcha/',
           'img_url' => base_url().'captcha/',
       );
       
       
        $data = create_captcha($vals);
       
        $_SESSION['captchaWord'] = $data['word'];
       
        $this->captcha_setting();


        // image will store in "$data['image']" index and its send on view page
        $this->load->view('captcha_view', $data);
     }

this is capcha_view:

Code:

<?php

echo $image;


?>

in the folder captcha there are more than 100 image created in one minute
