I am using a variable in a if statement and it is not recognizing it as a normal variable. Just gives me an error saying unknown variable $i. any ideas?

Code:
&lt;?php for ($i=1; $i<=$num_of_images ; $i++): ?&gt;

  // this $i does not work, unknown var

   &lt;?php if( $img->image.$i != 'nopic.jpg' ): ?&gt;

heres the full code

controller

Code:
$data['images'] = $this->main_mod->getImages();

$data['num_of_images'] = 8;

// views

$data['content'] = 'main/post';

$this->load->view('templates/main', $data);

view

Code:
&lt;?php foreach($images as $img): ?&gt;

   <p>&lt;?php echo $img->name; ?&gt;</p>

  &lt;?php for ($i=1; $i<=$num_of_images ; $i++): ?&gt;

  // this $i does not work, unknown var

   &lt;?php if( $img->image.$i != 'nopic.jpg' ): ?&gt; // if an image was uploaded by user

   <img src="&lt;?php echo base_url('assets/images/').'/'.$img-&gt;image . $i; ?&gt;" width="30" alt=""><br />

   &lt;?php endif; ?&gt;

  &lt;?php endfor; ?&gt;

&lt;?php endforeach; // end ?&gt;
