accesing post variables in array - php

Question

how can I keep post variables through all the functions in php class?
I'm accessing post variables in a array in function. But when I try to access those in another function it retrvies only the last element in array.
foreach ( $questionAry as $questionID )
{
$questionName = $this->htmlID_questionID . $questionID;
$question_answer = $_POST[$questionName];
$_SESSION['qusID'] = $questionID;
$_SESSION['qusanswer'] = $question_answer;
}
I want to access $questionID and $question_answer in another function. I tried to do it through session, but I can only access last value.

Your loop is wrong...these guys are getting overwritten on every iteration
$_SESSION['qusID'] = $questionID;
$_SESSION['qusanswer'] = $question_answer;
You need to use an indexed loop, something like so...
foreach ( $questionAry as $key => $questionID )
{
$questionName = $this->htmlID_questionID . $questionID;
$question_answer = $_POST[$questionName];
$_SESSION['qusID'][$key] = $questionID;
$_SESSION['qusanswer'][$key] = $question_answer;
}
EDIT: based on conversation below, try something like so.
function getvalues() {
$questions = array();
$jsonEncoded = ( get_magic_quotes_gpc() ) ? stripslashes($_POST[$this->htmlID_questionIDAry]) : $_POST[$this->htmlID_questionIDAry];
$jsonDecoded = json_decode($jsonEncoded);
$questionAry = explode(",",$jsonDecoded->list);
$instr = "";
foreach ( $questionAry as $key => $questionID ) {
$questions[$key]['name'] = $this->htmlID_questionID . $questionID;
$questions[$key]['answer'] = $_POST[$questionName];
}
return $questions;
}
$parsedQuestions = getvalues();
name_of_other_function($parsedQuestions);
function name_of_other_function($parsedQuestions){
print_r($parsedQuestions);
}
