I have two optimization question about the function include.
Is it better to use a single php file and include it or use several little files and include them? Which one will be faster?
For example, I use a PHP file with mysql_connect and all the db connection stuff. Then I include it when I need it. But will it be faster to just write the code when I need it and not include anything?
Also if someone has the actual numbers, I will be a nice plus.
The differences will be trivial.
Don’t repeat yourself. Do not put connection information in each file over and over again. Including sounds fine in your case.
Stop making use of
mysql_*(). Use PDO or MySQLi instead.You’re talking about micro-optimalisation, while it’s probably better to start thinking about object oriented programming instead.
