How to run a function within an echo call
<p>This is a quick but simple question. I am having a bad day and don't know how to do this:</p>

<p>What I need to do is this...</p>

<p>I am checking for PMD in the url if so echo this:</p>

<pre><code>&lt;?php 
        if ( isset($_GET['pmd']) ) { 
          echo"&lt;div class=\"response\"&gt;&lt;p style=\"width:350px; height:200px; vertical-align:middle;\"&gt;&lt;strong&gt;Thank you for acting as a &amp;quot;watchman on the walls&amp;quot; of Jerusalem! Your name will now appear on our virtual wall.&lt;br&gt;&lt;br&gt;You can also catch up on the latest news from Israel by visiting our news feed below.&lt;/strong&gt;&lt;/p&gt;&lt;/div&gt;";
        }else { etc...
</code></pre>

<p>What I need to include within that is an image like such that is firing off a tracking pixel.</p>

<pre><code>&lt;img src="url.com?cid=12345&amp;aid=1234&amp;oid=&lt;?php echo mt_rand(); ?&gt;&amp;quantity=1" height="1" width="1" /&gt;
</code></pre>

<p>What I would like to have is:</p>

<pre><code>&lt;?php 
        if ( isset($_GET['pmd']) ) { 
          echo"&lt;div class=\"response\"&gt;&lt;p style=\"width:350px; height:200px; vertical-align:middle;\"&gt;&lt;strong&gt;Thank you for acting as a &amp;quot;watchman on the walls&amp;quot; of Jerusalem! Your name will now appear on our virtual wall.&lt;br&gt;&lt;br&gt;You can also catch up on the latest news from Israel by visiting our news feed below.&lt;/strong&gt;&lt;/p&gt;
          &lt;br /&gt;
          &lt;img src="url.com?cid=12345&amp;aid=1234&amp;oid=&lt;?php echo mt_rand(); ?&gt;&amp;quantity=1" height="1" width="1" /&gt;
          &lt;/div&gt;";
        }else {
</code></pre>

<p>What do I need to do to get that mt_rand() function to fire?</p>

<p>Thanks,</p>

<p>Matt</p>
