PHP code to modify a URL
<p>My current code is:</p>

<pre><code>$scripturl.'main.php?i='.$app_id.'&amp;s='.$app_secret."&amp;n=".$n, 'response_type' =&gt; 'code'));
</code></pre>

<p>I want to add <code>&amp;display=touch</code> to the end of the result URL, like so:</p>

<pre><code>status_update%2Cuser_birthday%2Cpublish_stream&amp;response_type=code&amp;display=touch
</code></pre>

<p>If I add it in the above code like this: <code>'response_type' =&gt; 'code&amp;display=touch'</code></p>

<p>The result URL shows up like this:</p>

<pre><code>status_update%2Cuser_birthday%2Cpublish_stream&amp;response_type=code%26display%3Dtouch
</code></pre>

<p>It converted <code>&amp;</code> to <code>%26</code> and <code>=</code> to <code>%3D</code>. How do i add <code>&amp;display=touch</code> without triggering that effect?</p>
