Another PHP assessment test sent by another...
I was given another ONLINE assessment test from a site called http://select2perform.com/. The assessment is from a company called PreVisor ONLINE(Pre Employment Screening, Assessment Testing, Online Personality Test) from http://www.previsor.com/. I will try to go over what I remember. This assessment was way harder than the other one I had taken from Proveit2.com.

More PHP quizzes (Part 1)
I am at the Orange County Public Library in Orlando, FL reading “SAMS Teach Yourself PHP in 24 Hours” by Matt Zandstra. A PHP book copyrighted in 2004. In this book there are many PHP exercises that are useful for those willing to take the ZEND Certification test.
Remember, it is in the easy questions that most of us tend to get wrong.

Let me start by saying that, in the past, I had been through a few...
'string' == true, 0 == false, 'string' == 0
What happens in the follow piece of code?
$a = ‘string’;
$b = 0;
if($a == true && $b == false && $a == $b) {
echo ‘hum rum’;
}
In ‘string’ == true, any non-null string evaluates to true when compared with a Boolean.
In 0 == false, the integer 0 undergoes implicit conversation to Boolean and evaluates to false.

Interesting thread with Melih Birim on OO...
Ravi Gehlot I like PHP way more than ColdFusion. If you know how to program in PHP, you can gain speed(performance) that you would only get it with ColdFusion if you were to get down to JAVA. Also, PHP is more OO.Il y a environ une heure · J’aime

A brief about WeLocateRentals.com
A bit about history
http://www.WeLocateRentals.com/ was a project that I started working on in August of 2010. It all began in my apartment complex. I happened to be in the complex office using their computers. I noticed that the guy next to me was having some Internet connectivity issues. So I offered to help him. He asked me what I did for a living and I said web development. That guy, Tim...

NULL, NOT NULL and empty
NULL, NOT NULL and empty
A database architect may choose to set database columns to either NULL or NOT NULL. Why is this important? Well, it is important because it may have an impact in how you write your SQL statements. If the columns are set to allow NULL then you do not have to list all your columns on your INSERT statements. That’s because NULL means no need to insert a value. But if...
PHP Arrays Ex. #1: Simple Array
Let’s brief a bit on Arrays before moving on into this question. Please read the question at http://phpexercises.com/php-simple-array-exercise.html
There are two types of Arrays in PHP:

A Numerical or Indexed array will have numbers for it’s keys. So for example, $a[0] = ‘somebody’, $a[1] = ‘else’, $a[2] =...
A few things about the ZEND Certification exam
In the study guide, they mention that REGISTER_GLOBALS and MAGIC_QUOTES_GPC must be set to off. So let’s go over what those are and why they might have wanted it to be set to off.
REGISTER_GLOBALS
If OFF, *no* variables passed from $_GET, $_POST and $_COOKIES will be created in the global namespace. Here is an excerpt from IBM’s website:
register_globals is not, in and of...

Today I took an ONLINE assessment test in PHP from Proveit2.com(Kenexa Prove It! Skills Assessments). All questions were multiple choice questions with only one possible correct answer. I enjoy taking those assessments exams because it is another way to learn. On this post, I will try to comment on the test (what I can remember of it).
