Stephen, that page specifies the exact same line for the .htaccess that
he said he used. I'm not sure why it would cause an internal server
error, but I've seen some Apache configurations completely flake over
lines in the .htaccess that were fine elsewhere.
The only thing I can find online where this line will cause a server
error is where the server is set up to allow custom php.ini files which
override the defaults. To test this, try adding a php.ini file into the
directory your script is (this is completely untested, I just saw it on
a forum (http://www.bluehostforum.com/archive/index.php/t-15975.html ))
and enter the regular php.ini line to turn it off.
If that fails, I'd try and contact your hosting provider and see what
they say, as they probably have more information specific to this
problem, as it's most likely a setting of theirs that is causing it.

Have you tried:
ini_set('magic_quotes_gpc', false);

I'm trying to set it directly and not have to incl in every script I write.

Solved.
Had to have my host provider put a copy of php.ini in my public_html and
then I made the magic quotes setting change.
Interesting - running a phpinfo command still shows the setting as On
becuase it returns the server's settigns, NOT my individual folder setting.

That won't work, because by the time the server comes to process the
script, the data has already been processed. In effect, that line will
do nothing.

If $correct_answer has a value of 3 what is the correct syntax needed to use
echo to display the value of $trivia_answer_3?
I know this is incorrect, but along the lines of what I am wanting to do:
echo $trivia_answer_$correct_answer;
$trivia_answer_1 = “1,000”;
$trivia_answer_2 = “1,250”;
$trivia_answer_3 = “2,500”;
$trivia_answer_4 = “5,000”;

Best bet would to toss this into either an object or array for simplification,
otherwise that type of syntax would need the use of eval.
example: eval('echo $trivia_answer_'.$correct_answer.';');
best bet would be to..
$trivia_answer = array();
$trivia_answer[1] = 1000;
$trivia_answer[2] = 1250;
$trivia_answer[3] = 2500;
$trivia_answer[4] = 5000;
echo $trivia_answer[$correct_answer];

You can use variable variables [1] to access the variable by building its
name in a string:
$name = 'trivia_answer_' . $correct_answer;
echo $$name;

echo $trivia_answer[$correct_answer];
Agreed the OP's value list isn't optimal, but eval is not needed to
address the solution:
<?php
$trivia_answer_1 = "1,000";
$trivia_answer_2 = "1,250";
$trivia_answer_3 = "2,500";
$trivia_answer_4 = "5,000";
$answer
= isset( ${'trivia_answer_'.$correct_answer} )
? ${'trivia_answer_'.$correct_answer}
: 'Not found';
echo $answer."\n";
?>
Cheers,
Rob.

Not completely obvious to me what you're trying to do but I assume its:
echo '\$trivia_answer_' . $correct_answer . " = \"" . $somevalue . "\";";

You could do:
$var = "trivia_answer_.$correct_answer";
echo $$var;
But I agree that an array would be simpler.
best bet would be to..
$trivia_answer = array();
$trivia_answer[1] = 1000;
$trivia_answer[2] = 1250;
$trivia_answer[3] = 2500;
$trivia_answer[4] = 5000;
echo $trivia_answer[$correct_answer];
You can define this a bit more simply:
$trivia_answer = array (
1 => 1000,
2 => 1250,
3 => 2500,
4 => 5000
);
You can do it even more simply by just giving the values, but indexes wil
start at 0:
<?php
$trivia_answer = array (1000, 1250, 2500, 5000);
print_r ($trivia_answer);
?>
Array
(
[0] => 1000
[1] => 1250
[2] => 2500
[3] => 5000
)
While manually defining an array like this is only slightly less tedius
than using 4 numbered variables, it's a lot easier to do if you're getting
data from somewhere else (e.g. a database of trivia questions). To use
the original way proposed, you'd have to keep constructing variable names,
which arrays avoid quite nicely.
In my opinion, the only real usefulness for a syntax like $$var (above) is
if you want to do something with a bunch of variables in one go. For
example:
foreach (array ("title", "artist", "album", "label") as $field)
echo ucwords($field) . ': ' . $$field . '<BR>';
The above comes from a function which manages only a single record, so no
real need to use an array. I could of course, e.g. record['title'] etc,
but I don't see much could be gained unless I needed to be able to manage
an entire record as a single unit.

A while back, I did a project in Java where parts of it had to access and
process streams. I guess this would be a really good exercise for me to see
if it's doable in PHP also. In addition to implement 'PHP simulating
threads', in this scenario, where 1 thread would download and monitor the
streams while another thread would analyze/process the data and import into
a database.
