But there was one flaw in that technique you have had to change the file extension explicitly but in this post I’m going to show you how to rewrite the URL instead of renaming the file extension Using this technique you will see product.html in the address bar of the browser but the actual file name remains product.php and you don’t need to rename the file extension. Furthermore you can rewrite the URL like product.php?id=5 to product-5.html.
