Wow! Five whole months of the OpenLampTech newsletter! This week’s issue is loaded once again with great PHP/MySQL content. Cheers and here is to many many more future issues!

Receive a free copy of my eBook, “10 MySQL Tips For Everyone”, when you subscribe to the OpenLampTech weekly newsletter. Both are free so what’s not to love?

In this week’s OpenLampTech newsletter, we have content covering:

  • Finding the backdoor of a hacked WordPress site
  • Setting SQL_MODE in MySQL
  • Strings to dates in PHP
  • Handy INFORMATION_SCHEMA queries in MySQL
  • PHP access modifiers
  • And much much more

I write about SQL, PHP, and CodeIgniter regularly over on my technical blog, Digital Owl’s Prose. Follow me there for similar content and be sure to sign up for my free weekly newsletter (and ebook), OpenLampTech, the newsletter for PHP/MySQL Developers. Thank you!
