Some of these tips may very well be dated compared to the latest versions of PHP. I know there's a lot of debate about single versus double quotes, which is why I included that tip at the end where other guides may have included it at the beginning. Out of curiosity, did you test the others, and, if so, how did they pan out? Thanks for testing, PERECil. Some of these tips may very well be dated compared to the latest versions of PHP.

For example, you might set up a MySQL database, propagate it with your pricing information, and pull the data into a $prices array with something simple like this: <code><?php mysql_connect('hostname', 'username', 'password'); mysql_select_db('decking_prices_db'); $prices = mysql_query("SELECT product_id, price FROM decking_prices"); $price = array(); while ($price_data = mysql_fetch_object($prices)){ $price[$price_data->product_id] = $price_data->price; } mysql_close(); ?></code> Without knowing more about your setup, Texx, I can’t say for sure, but my gut tells me that moving your included information into a database and pulling it out with a query would vastly simplify things for you.

Using $_POST['somevariable'] over say $somevar = $_POST['somevariable'] and then accessing $somevar many times is much slower than just using $somevar. PHP has to lookup the name in the POST array each time. Re point 7, needlessly copying variables.

Didn't see any difference when switching from (include|require)_once to (include|require). Tested on a test website with more than 20-30 requires. 10.
