Can anyone recommend a good website for online PHP tests for potential employees?
Thanks in advance.

Aha, so we were thinking of different definitions after all.
I was thinking of ways that users can submit them, whereas you are thinking of ways that PHP can access them.
Both are valid, and have different answers.
system — 2010-02-04T06:42:59-05:00 — #3
Methods cannot be used simultaneously, that's all.
Because we have only one definition for the things.
Also there are no thing called "get data" actually. It is query string data to be correct.
And it is just PHP creators fail, to name $_GET array this way, that confuses many developers.

Currently some large internet hosts are down, however a search for timed php quiz does give us some promising sites. For example:
PHP Quiz - free online quiz, test and trivia
Such sites would give you insight as to how such things are handled, from which you may be inspired to create your own.
system — 2010-02-04T06:33:04-05:00 — #5
The term "method" has only one definition.
But poor PHP folks get confused by superglobal arrays names
paul_wilkins — 2010-02-04T06:35:28-05:00 — #6
Please carry on. What is a good explanation for the question.
paul_wilkins — 2010-02-04T06:21:45-05:00 — #7
That depends on how you define things.
While you can pre-populate the querystring with some values when you use post, that might not count as "get" data because no data from a web form can be sent via get simultaneously with post.

Thanks for your replies guys.
We could quite easily provide a list of questions, but we're after a resource where they could complete the test from home, so ideally there would need to be a timer for each question and we could then look at how they scored.
Just wondering whether any employers could recommend this type of system, could always develop it ourselves, but just don't have the time!
Thanks again for your replies.

What are the differences between Get and post methods
My favorite is "Can we use both methods simultaneously?".
Most people fail to right answer
system — 2010-02-04T07:00:11-05:00 — #11
Method has only one definition. No thinking required.
That's why it is good question.
It requires understanding of things.
Much like cookies does. Another seems-to-be-simple question: What is cookie?
system — 2010-02-04T07:03:44-05:00 — #12
Crabby, you can just accept ZCE certificates as passed tests.
paul_wilkins — 2010-02-04T07:03:57-05:00 — #13
A cookie is just data that is stored against a (sub)domain.
The term originated from the process of manufacturing.
If we're not going to help the OP with his question though, we should take this off-thread.

Thanks again for your replies
I just took a test at the link you provided pmw57
My answer's right too isn't it??? 8>)
2) PHP comments for a single line have the following syntax:
a) /* comments /*
b) # - correct answer
c) (your answer) //
paul_wilkins — 2010-02-04T07:16:19-05:00 — #15
Something that I have seen before that works really effective for the presentation, is to place to the left of the alpha bullets a green tick mark or a red cross.
The answer can use a different color for correct line, but also should indicate in a color-free manner the right answer, with a tick to the right of it.
system — 2010-02-04T07:16:54-05:00 — #16
There are some other mistakes too.
I can't believe you're looking for well-cared tests for free, don't you?
paul_wilkins — 2010-02-04T07:22:12-05:00 — #17
Ahh, that's a nice trap. The test creator must have been in a snotty mood that day.
echo 'This is a test'; // This is a one-line c++ style comment
/* This is a multi line comment
yet another line of comment */
echo 'This is yet another test';
echo 'One Final Test'; # This is a one-line shell-style comment
crabby80 — 2010-02-04T07:24:05-05:00 — #18
I didn't mention 'Free'?
If there's a subscription cost then so be it, I was just wondering if anyone could recommend anything they've used??
crabby80 — 2010-02-04T07:27:01-05:00 — #19
Lol, actually I never knew you could use a hash for a comment...8>)
system — 2010-02-04T07:28:01-05:00 — #20
3 and 22 also has wrong answers.
As for cookie, it can be not stored at all, especially answer's one.
Cookie is an HTTP header, nothing else.
