title: issues with Iframe and php include
body: <p>I'm new to PHP and i use the include function to include a header file that has my db connections and my menu. On a body page I'm using a iframe to include a aside that needs to go on many different pages. The issue arises when i hit click on one of the hyperlinks of the aside that is in the IFRAME it will take me to the proper page BUT will RE-include the header in that portion of the code. I was wondering if there is any alternatives OR ways to insure the header doesn't reload in my iframe. Here is a copy of my code.</p>
  
  <p>Main PAGE</p>
  
  <pre><code>&lt;?php 
  include_once("include/header.php");
  
  ?&gt;
  &lt;div id="content"&gt;
   &lt;div id="left" class="sidebar"&gt;
  &lt;iframe src="aside.php" height="550" frameborder="0" width="210" scrolling="no"      allowtransparency="true" rel="nofollow"&gt;&lt;/iframe&gt;
   &lt;/div&gt;
  </code></pre>
  
  <p>Aside page</p>
  
  <pre><code>&lt;div class="imgholder"&gt;
        &lt;p class="employeename"&gt;Pablo Israel Penaloza&lt;/p&gt;
        &lt;img src="img/Pablo-Peñaloza.jpg" width="202" height="150" class="imgemployee"&gt;
        &lt;div class="sidebarmenu"&gt;
      &lt;ul id="sidebarmenu1"&gt;
            &lt;li&gt;&lt;a href="personalinfo.php"&gt;Informacion Personal&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Contacto&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Contact de Emergencia&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Dependientes&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Imigracion&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Deberes&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Salario&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Supervisor&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Calificaciones&lt;/a&gt;&lt;/li&gt;
            &lt;li&gt;&lt;a href="#"&gt;Membresias&lt;/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
          &lt;/div&gt;
      &lt;!--End sidebarmenu1--&gt; 
    &lt;/div&gt;
  </code></pre>
  
  <p>Thank you </p>
