If you were a fan of the PHP quizes that Mark van der Velden has posted in the past, you'll be happy to know he's come back with part four of the series after a bit of a hiatus.

It has been a while, but here is part 4 of the PHP Quiz series! A few questions to crack your brain about, or perhaps you know them all? Try them and find out! Also do read the idea behind these quizzes, here: The PHP Quiz series

In this quiz he tests your knowledge of class visibility, fluent method handling, class extension, strptime and a tricky "for" loop. Take the quiz and see how you do.

Mark van der Velden has posted the third part of his "PHP Quiz" series to test your mental muscles on various PHP-related questions.

Welcome to another part of the PHP Quiz series, again some interesting questions to crack your brain about. If you have some nice additions or questions, be sure to leave a comment. Enjoy part three!

Questions in this edition cover unset, form output, working with strings, references, globals and working with class inheritance. You can check out part one and part two for more brain teasing fun.

Mark van der Velden has posted another PHP quiz you can used to test your knowledge of the language:

A short quiz this time, but that doesn't make it less fun. Do you know the answer to all of them? Get a cup of coffee and kill 10 minutes with round two... As always, think of the answer before you execute the code or look it up. You can find round one here.

This one has questions on arrays, ArrayAccess, references, operator precedence and nesting structures. There's no answer key, so you'll just have to test it out if you want to see the answer.

Blake has posted some of his opinions on "best practices" that can help you land that new job you've been looking for:

The last couple of weeks have been quite the experience for me. I was part of a big layoff at my former company, which was interesting. I've never been in that position before, and it's hard not to take it personally. [...] Before the face-to-face portion, I chatted with the owner and head programmer on a conference call, and they ended up sending me a technical assessment quiz.

In the quiz, there was one question the prompted him to come up with his tips - ten things that you can do to keep your code clean, lean and easy to maintain. His tips include things like "use single-quotes around array indexes", "don't use open short tags" and "document your code". Some of the suggestions don't make that much of a difference, but others (like the documentation one) can make the world of difference down the line.

Tobias Schlitt has posted about the eZ Components book on his blog today - including how you can win a copy of your very own!

On the Zend Developer Zone, there's a new post that has the info on how you could get your hands on a free copy of Zend's Studio software (a $300 USD value).

My good friend Avigail was kind enough to cough up some copies of Zend Studio and even a license for Zend Guard. [...] We've got a quiz (No, not a survey, a quiz!) to test your mad Zend Studio skillz. If you don't have said skillz, I'd suggest downloading the Free 30 Day Trial of Zend Studio and develop them.

Once you are a Studio-Fu master, take the quiz by clicking on this link.

For anyone that attended his talk at the International PHP Conference and were wondering what the answers to his quiz were, wonder no more. Christopher Kunz has posted the answers in his latest blog entry.

If you need a little explanation on the PHP Security Quiz by Mayflower, just read the extended entry. Just as a quick hint for the answers, I decided to blog about which answer is right - and why.

There's only four questions to the quiz, but it's good that he explains each. Some of them, especially dealing with regular expressions and Javascript attacks need a bit of explanation.

For those that couldn't make it out to the conference, here's the questions that match up with those answers.
