variable scope / session question

[r0k3t]

Hi there,

OK - I understand about scope for the most part, function foo can't access function bar's variables. But I thought I could stick a variable in the $_SESSION array and access it anywhere I tried but that doesn't seem to work. If I do a var_dump($_SESSION) in the function I see all the variables I have set. If I do it in after the function executes it is empty. These variables don't get set on the next page either.

Can someone point me in the right direction on this? In other programming languages If I set a global variable from inside a function then I have no problem.

Here is the function in question
function createSicList($studyNumberObj){

        $sicObjArrayCounter = $_SESSION['sicObjArrayCounter'];
        $masterSicArray = $_SESSION['masterSicArray'];

        $studyNumber = $studyNumberObj->getStudyNumber();
        if($studyNumberObj->getFirst_Previous_study()){
                $stdNum = $studyNumberObj->getFirst_Previous_study();
                //Set the value of $match if we find the word new...
                preg_match('/NEW/', $stdNum, $match);
                //if $match has a value skip over it
                if(!$match){
                        $First_Previous_Number = $studyNumberObj->getFirst_Previous_study();
                        $firstPreviousSICNumArray = getPreviousStudySIC($First_Previous_Number);
                        $masterSicArray[$sicObjArrayCounter] = $firstPreviousSICNumArray;
                        $sicObjArrayCounter++;
                }
        }
        $_SESSION['sicObjArrayCounter'] = $sicObjArrayCounter;
        $_SESSION['masterSicArray'] = $masterSicArray;
        echo $_SESSION['sicObjArrayCounter'];
        var_dump($_SESSION); //I can see everything from this var_dump
}
var_dump($_SESSION); //$_SESSION['sicObjArrayCounter'] and $_SESSION['masterSicArray'] have no value.
?>


Thanks... Ken

If you don't execute the function, the values aren't stored.

Try this simple test:
[code]<?php
session_start();
function test()
{
        $_SESSION['one'] = 'two';
        $_SESSION['two'] = 'three';
}
echo 'before<br>';
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
test();
echo 'after<br>';
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
?>[/code]
