Welcome to the Part 5 - final part of the series on MySQL Functions. I hope you've enjoyed it(or at least found it useful so far. You might want to check out Part 1 - Date and Time Functions, Part 2 - String Functions, Part 3 - Fun With Numbers or Part 4 - Make Functions with Stored Procedures & Triggers, in case you have missed any of them. In this final part, I thought I'd take a quick look at how MySQL performs in terms of speed versus PHP.
