Adding Spaces to Numerals
<p>I'm trying to add a space between any numbers that are passed over. Basically if <code>$var2</code> was <code>1028</code> I want it to add a space so that it becomes <code>1 0 2 8</code>. I only want it to add it for numerals though and not letters. I only need it to do it on <code>var2</code>-<code>var5</code> and nothing above that. Any help is greatly appreciated! Thanks!</p>

<pre><code>$apikey = $_GET['apikey'];
$campaign = $_GET['campaign'];
$phone = $_GET['number'];
$delay = $_GET['delay'];
$name = $_GET['var1'];
$var2 = $_GET['var2'];
$var3 = $_GET['var3'];
$var4 = $_GET['var4'];
$var5 = $_GET['var5'];
</code></pre>
