PHP 5 Advanced: Visual QuickPro Guide (2nd Edition)-->Errata
Unfortunately, despite the best efforts of myself, the technical editor, the copy editor, and the line editor, despite the multiple revisions, errors still occur. This page lists all the errors found in the book.
Note: errors are corrected in subsequent printings and therefore your particular copy may not contain all of the following.
You may also find the solution to your problem by using the book's corresponding forum. Signficant changes in the technology will be addressed there and you can also find problems and solutions encountered by other readers.
Known Errors in the Book:
| Chapter | Page # | Description | Date Added |
| 1: Advanced PHP Techniques | 10 | The "tasks" table definition as is won't work properly. When the date_completed column is updated, it also updates the date_added. This occurs because MySQL updates the first TIMESTAMP column in the table when that record is inserted or updated. The solution would be to define both date_added and date_completed as DATETIME, then change the INSERT queries to set the date_added column to NOW(). | August 30, 2007 |
| 1: Advanced PHP Techniques | 15 | On the second line of code under Step 9, the word "its" should not be there. The corresponding script is correct. | April 01, 2007 |

| 6: Basic Object-Oriented Programming | 238 | On line 20 of Script 6.1, and in the code under step 5, the Dutch version should be Hallo, wereld!. This also affects Figure 6.1 on page 243. | May 14, 2007 |
| 6: Basic Object-Oriented Programming | 250 | In the last Tip, it should say that both rectangles have the new dimensions as $r1 and $r2 refer to the same object. In PHP 4, $r1 and $r2 would be two different objects. | July 10, 2007 |
