answers$n. php tries to concate the constant answers with the variable
$n, but you forgot the concatenation operator ".".
i assume that answers should be a string and
is not a constant, therefore $answer["answers".$n] is right.
if answers is a constant use $answer[answers.$n];
but a better way of what you try to accomplish would be a array
using two dimensions:
$answer["answers"][$n]
$answer["question"][$n] ...etc
or if you only have "answers" as key use:
$answer[$n]
if you want to send form data as array, using more than one dimension,
do the following:
<input type="text" name="answers[answer][1]" value="">
<input type="text" name="answers[answer][2]" value="">
<input type="text" name="answers[answer][3]" value="">
or
<input type="text" name="answers[answer][]" value="">
<input type="text" name="answers[answer][]" value="">
<input type="text" name="answers[answer][]" value="">
Which is pretty much the same.
now on the processing page you can do:
ForEach($answers as $val) {
Foreach ($val as $answer) {
// do something with one of the answers
}
}

Hey guys,
i'm getting this error whe i try to access this variable. $answers[answer$n]
Parse error: parse error, expecting `']'' in
/home/blindtheory/web/quiz/add_quiz/add_quiz_process_2.php on line 36
the variable $answer[answers$n] comes from a form on the preceding page in
which a number of answers has been entered. the number of answers is up to
the user and can vary from 2 to 15. not the $n comes from a for loop whcih
enteres the answers into a database since i do not know how many answers
each
user has used.
why am i getting this error?
and is there a way around it?
following is the for() loop in which this story takes place.
thanks
Jule
