php check if link has been clicked
<p>Hi I'm a novice at php could some please help. I'm making a website it has a menu, I need it so that if a link like "link1" is clicked page1.php will load into the the mainSection div and if link2 is clicked page2.php will load in mainSection etc. so all the pages: page1, page2, page3 etc will load into this single page depending on what link has been clicked. Is this possible I don't know where to start. Thanks</p>

<pre><code>    &lt;body&gt;
        &lt;?php
            &lt;ul&gt;
                &lt;li&gt;&lt;a href="#" name="link1"&gt;link 1&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#" name="link2"&gt;link 2&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#" name="link3"&gt;link 3&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#" name="link4"&gt;link 4&lt;/a&gt;&lt;/li&gt;    
            &lt;/ul&gt;
        ?&gt;

       &lt;div id="mainSection"&gt;
            &lt;?php
        if (link1 == true){
             include 'page1.php';
        }
        if (link2 == true){
            include 'page2.php';
        }
        if (link3 == true){
            include 'page3.php';
        }
        if (link4 == true){
            include 'page4.php';
        }
            ?&gt;  
        &lt;/div&gt;
    &lt;/body&gt;
