Whats the difference between these two lines in PHP....Are they both variables?
<p>There's:</p>

<pre><code>$myvar="somthing";
</code></pre>

<p>and:</p>

<pre><code>define('myvar', 'something');
</code></pre>

<p>I know the first one is defining a variable and I thought the second one was too, until someone told me its not...</p>

<p>Whats the difference between the two? They both do the same things right?</p>
