title: IF statement not working with OR
body: <p>For some odd reason, I can NOT debug this for the life of me..
  $this->input->post('post_page') = 10.... I echo the variable and it does print 10 to the screen.
  This keeps returning false when it should be true..
  So... can someone help me out with this? I tried putting individual parentheses around each check AND changing the || to OR.. still nothing.</p>
  
  <p>Here is my code nonetheless:</p>
  
  <pre><code>if($this-&gt;input-&gt;post('post_page') &lt;&gt; 10 
                  || $this-&gt;input-&gt;post('post_page') &lt;&gt; 25 
                  || $this-&gt;input-&gt;post('post_page') &lt;&gt; 50 
                  || $this-&gt;input-&gt;post('post_page') &lt;&gt; 75) {
              return false;
          }
  </code></pre>
