A useful class I picked up somewhere, and possibly modified in the years since, that handles the work of file uploads. I’ve found it very useful, so hopefully you will to.

I try to use a central database class in my code, simply because if I ever need to migrate from MySQL to another database engine (such as Microsoft SQL or Postgres), all I have to do is alter the one database class file and my application is all converted. Since everything goes through the database class, it’s the only file you need to change in such an instance.

I find it’s always useful to keep this functionality in a function. This example relies on some global variables …pretty easy to understand.

Need to get a list of files from a folder on your server? Maybe it’s a list of photos that you want to manipulate with PHP, this function will grab all files from a specified directory and return them in an array for you.

Something I struggled to find when starting out was good, non standard encryption and decryption functions. Here’s a couple for you to use/adapt as you wish.
