How can i setup my php code to change my CSS background picture daily : <p>I have a website that has a background, and i want it to change daily.</p>

<p>In my directory I have a background. each background has a number at the end.</p>

<pre><code>././background1.jpg
</code></pre>

<p>In this case this file has a 1 tacked to it. So depending on the day the php will rewrite the css such that on a new day a new background will be set.</p>
