Ok, I was going to give this a try, even after several issues, but I completely stopped on the question that asked the output of the following:
Code: Select all
echo date("Y-m-d:H:i:s",strtotime($datetime));
none of answers to choose from gave the month as 2 digits, which is what
m produces.
It is a nice idea for a site, but this was far from something that says it was professionally done, from the signup form just kicking me back to the home page, complete with the big "Sign up" buttons still there, making me think it broke, to code display issues on questions (ex. clearly showing closing PHP tags then not showing the opening PHP tag before the next section of PHP code. So if you are showing the closing, I expect the opening, otherwise the "output" you ask for will be the actual code you see since PHP was never restarted. Also wording was bad on some questions, like asking "What is the return value of this substr function? " yet you have more than one...
Sorry, nice idea of a site, but as a PHP developer for 12 years, programmer for 20 years, and have taken a few online certification exams, this just really needs a lot of work.

Ok, I couldn't resist, I continued on, not actually answering them, but looking at the questions....
"If you used $_SERVER['PHP_SELF'] function in your page, then what is the return value of this function" $_SERVER['PHP_SELF'] is NOT a function
You ask about $_SERVER['REMOTE_ADDR'] and one of the answers is the IP of the visitor. This is probably what you are looking for, but that is not always the case it is the IP of what is connecting to your script. I use a VPN a lot, so you will get the IP of my server, not my actual IP address. Yes this is nit picking, but you are claiming to certify people as experts, something like that makes a difference.
Ok, so I get to the end, knowing i wouldn't pass as since I got the one question, I just kept choosing the first option on each one...
Sorry, you failed!
Your result is better than 100% of those who took this test.
Your mark is 50. You can see the detailed results below:
The detailed results was nothing but a bar code showing "46.67%"....

PS. for anyone wanting to try it but don't want to give real info, the site doesn't do any activation, so you don't need to give a real email address
