Php, wait 5 seconds before executing an action
<p>I have a .php script that I use for creating the list of my products.
I am on shared hosting, so I can't do a lot of queries otherwise I get a blank page.</p>

<p>This is how I use my script now:</p>

<p>script.php?start=0&amp;end=500&amp;indexOfFile=0  ->> make a product0.txt file with first 500 products</p>

<p>script.php?start=501&amp;end=1000&amp;indexOfFile=1 ->> product1.txt file with another 500 products</p>

<p>script.php?start=1001&amp;end=1500&amp;indexOfFile=2 ->> product2.txt file with last 500 products</p>

<p>How can I modify the script so it will make all these files automatically, so that I don't have to change each time the link manually?</p>

<p>I would like to click a button which will do this:
make the product0.txt file with the first 500 products
wait 5 seconds
make the product1.txt file with with another 500 products
wait 5 seconds
make the product2.txt file with the last 500 products</p>
