Do get a list of all found corrections, check out the corrections category.
Do you have a correction or clarification? Did you find a mistake, an error, or something else that shouldn’t be there in the book? Well, go ahead and leave a comment on this page and I’ll probably turn it into a post! Thanks for helping out, and I’m sorry that neither myself nor my reviewers caught the mistake!







Mario,
The function index shows array_key_exists: 82. It’s actually on page 79.
Hi Mario,
Do you plan to make a similar book about OOP and Advanced PHP? I am a newbie myself, but I would like to know. Thank you so much Mario for your great and valuable book. Please keep up the good work.
