Notices when executing script?
<p>Why do I get notices when I execute a php file on my local server? Does that mean there is an error in my file? Notices like:</p>

<pre><code>Notice: Use of undefined constant l - assumed 'l' in C:\xampp\htdocs\weekday.php on line 3  
Notice: Use of undefined constant Monday - assumed 'Monday' in C:\xampp\htdocs\weekday.php on line 6*
</code></pre>
