Deleting a Record, 3rd paragraph. |
I don't see an else statement in the code.
Note from the Author or Editor:
Paragraph three in the section "Deleting a Record" should read:
If $delete didn?t contain the word ?yes,? then the following statements are executed. $query is set to an INSERT INTO command, followed by the five values to be inserted. The variable is then passed to mysql_query, which upon completion returns either TRUE or FALSE. If FALSE is returned, an error message is displayed. |

Pseudoclasses & Pseudoelements |
I was confused about the difference between Pseudoclasses and Pseudoelements. I went to the provided link and I see that the book just had things a little mixed-up. Wikipedia was also helpful,
http://en.wikipedia.org/wiki/Cascading_Style_Sheets
"A pseudo-class classifies document elements, such as :link or :visited, whereas a pseudo-element makes a selection that may consist of partial elements, such as :first-line or :first-letter."
Note from the Author or Editor:
I have tightened up the explanation about he difference between pseudo classes and elements in future editions of the book. |

With the release of Zend Server 6, Zend Server Community Edition (Zend CE) has been replaced with a new product called Zend Server Free Edition. It offers all the same functionality (and more), but installs and sets up slightly differently than the manner described in the book.
Therefore the tinyurl.com link given for the previous product, doesn't work, but you can get the new free server from the following URL:
http://zend.com/en/products/server/free-edition
Or the shorter:
http://tinyurl.com/zendfree
To take this development into account I have completely rewritten Chapter 2 around the new Zend Server Free Edition, and have uploaded a PDF of the chapter to the following URL:
http://lpmj.net/ch02.pdf
Please refer to this version of the chapter instead, particularly if you're using a Mac, as the MySQL install is now actually a little easier because there's less command line configuring to perform.

Although stated elsewhere that installation of Zend may change during the lifetime of this edition the problem I have requires more than common sense. Zend 6 no longer gives the option to download phpMyAdmin. Is this a problem? It would be nice to have an explanation on how to download and configure it manually.

Top of page first sentence in first paragraph in relation to Figure 2-21 |
"As you can see from Figure 2-21, Editra highlights the syntax appropriately using ""colors"" to help clarify what's going on."
*This page, and all other pages in this book with PHP code examples probably should have been printed in color for Figure 2-21 and other examples. I am guessing that the original master proof of this was in color and when it went to print everything was flattened to Black & White (Greyscale).
I selected Minor Technical Mistake because it will not lead anyone wrong, but since it states as you can see from the colors and its all in greyscale I figured this should be shared with you.
If this is in color in the PDF version that I see from the drop down of product formats and since I already bought this book New at Amazon.com, if a copy of this PDF in color is available, that would be greatly appreciated to use side by side with this book as well as when working on code.
By the way I am currently at chapter 3 and greatly enjoying this book to learn PHP with MySQL, JavaScript, and CSS. Just received it today in the mail. I have other older programming books by O'Reilly and I feel they are the best books out there to learn from and use as references on projects.
Thanks for taking the time to read this and possibly correct to color printed figures in a 3rd edition on the book.
Note from the Author or Editor:
in the next edition of the book I will note that you can see shades of grey in the figure in the printed version. |

"spread out across the wo"
I'm using the kindle edition(2nd edition) of the book and through out the book characters seem to have been cut off.
I've tried multiple devices ranging from PC, mac, iPad, Nexus 7 and all of them are showing the same issue.
I've deleted the book from my devices and re-downloaded it again, but it still shows the same issues.
Also with chapter 2 you might want to include this link http://files.zend.com/help/Zend-Server-6/content/installing_phpmyadmin.htm as the book talks about phpMyAdmin later on and yet phpMyAdmin is not installed during the zend server installation and needs to be installed as an app after that.

3rd paragraph under Data Types |
Under Data Types, the term "bytes" was used without an explanation as to what that is. A little bit further, the BINARY data type was explained using bytes, which only caused more confusion. Could you explain what bytes are? My guess is it's a measure of size but I need a little further explanation.
Note from the Author or Editor:
I will take your request under consideration for the next edition of the book. Essentially a byte comprises 8 bits and can have the values 00000000 through 11111111, which are 0 to 255 in decimal. |

So, I've been trying quit hard to get mysqldump to work and just when I was about to give up I wondered if there was an "issue" with zend itself.
Essentially, I was receiving the following error when I tried to get mysqldump to work on my mac osx terminal:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) when trying to connect
My sleuthing found this blog:
A while ago I installed Zend Server Community Edition on OS X which was pretty straightforward. It was only recently that I found out that, as opposed to mysql which worked fine, mysqldump didn?t work correctly and terminated with the error:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) when trying to connect
Inspecting the mysql configuration contained in /usr/local/zend/mysql/data/my.cnf confirmed that the section [client] showed the socket as returned by executing SHOW VARIABLES; from the mysql client: /usr/local/zend/mysql/tmp/mysql.sock
Although it is possible to specify the socket by using mysqldump?s --socket switch, that doesn?t really seem a ?solution?.
Apparently mysqldump, as opposed to the mysql client does not use the server-specific settings contained in /usr/local/zend/mysql/data/my.cnf. The comments in my.cnf state:
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/zend/mysql/data) or
# ~/.my.cnf to set user-specific options.
After copying /usr/local/zend/mysql/data/my.cnf to /etc/my.cnf mysqldump worked as expected.
In /etc/my.cnf I have included only the setting needed to get mysqldump running:
# Specifying socket to use for mysql/mysqldump
# For other settings refer to /usr/local/zend/mysql/data/my.cnf
[client]
socket = /usr/local/zend/mysql/tmp/mysql.sock
Hope this saves anyone running into the same issue some time.
Update (alternative solutions):
As Joel Clermont pointed out it is also possible to create a symlink on the socket location expected by mysqldump to the real socket location. This can be done by executing:
ln -s /usr/local/zend/mysql/tmp/mysql.sock /tmp/mysql.sock
Another possible approach is to create a symlink at /etc/my.cnf to /usr/local/zend/mysql/data/my.cnf. This has the downside that it requires loosening the default permissions (drwxr-x---) on the data folder by allowing ?others? to enter it. Commands to execute:
sudo chmod o+x /usr/local/zend/mysql/data
sudo ln -s /usr/local/zend/mysql/data/my.cnf my.cnf
Granting more permissions can be a security consideration but on most development setups this probably won?t be an issue.
Long story short I typed in:
ln -s /usr/local/zend/mysql/tmp/mysql.sock /tmp/mysql.sock
then
mysqldump/usr/local/zend/mysql/bin/mysqldump -u USER -pPASSWORD publications
and FINALLY got it to work.

Thanks for your sleuthing. I will address this in the next edition of the book. |

Example 10-2 |
When browsing the PHP documentation, I saw that the original MySQL extension was being deprecated in favor of the newer MySQLi extension. Aside from the object-oriented interface and some new features, how much does the new extension differ from the original?
This is a wonderful book. As a beginning web designer from Python and Java backgrounds, I've found it surprisingly simple to learn the basics of programming the Web 2.0. Thanks, Robin Nixon and O'Reilly!
Cheers,
Jordan
Note from the Author or Editor:
Indeed the MySQLi extension is now recommended in preference to the old MySQL procedural extension. However the old method is deprecated but will continue to be supported for some considerable time.
The next edition of this book will follow the latest recommendations, regarding MySQLi. |

"Bringing it all together" |
I was just re-testing the "Social Networking Site" final project and found something odd in regards to one's username.
Essentially, the program will allow you to login (with correct password) in regardless of how certain letters are capitalized... which is ok, I guess
Problem:
1. The change shows in the "Messages"
for example:
User wrote: Bah bah
usER wrote: Etc. Etc.
USER wrote: Goose [erase]
(currently logged in as USER)
The next odd thing is that the way I type my username enables me to delete messages only from THAT username. For example above, if I login as "USER" only messages from "USER" can be erased. I have to log out and log back in as "User" to be able to delete under that name (again, password is the same and the system recognizes me as the same user).
I have tried to go back and modify as necessary, but, alas, made things worse. I'm still at it and hopefully before Robin gets back I'll post a response.
Note from the Author or Editor:
