How can I unserialize data from database after it was serialized - sql

Question

try {
if (isset($_SESSION['list']) > 0) {
$test = serialize($_SESSION["list"]);
$sQuery = "INSERT INTO table (id, date) VALUES ('$test', NOW())";
$oStmt = $db->prepare($sQuery);
$oStmt->execute();
}
else {
echo 'No data';
}
}
In my database I see this:
1 a:1:{i:1;s:1:"5";} 2011-12-21
The $_SESSION['list'] stores ID and the QUANTITY.
The data a:1:{i:1;s:1:"5";} is as follow: i=id, s=id:"quantity", I read this as id=1 and the quantity of id=1 is 5, am I correct?
Now I want select the data and unserialize the array.
try {
$sQuery = "SELECT * FROM table";
$oStmt = $db->prepare($sQuery);
$oStmt->execute();
while($aRow = $oStmt->fetchALL(PDO::FETCH_ASSOC)) {
$id = unserialize($aRow['id']);
foreach($id as $id => $quantity) {
echo $id.', ';
}
}
}
catch(PDOException $e) {
$sMsg = '<p>
Regelnummer: '.$e->getLine().'<br />
Bestand: '.$e->getFile().'<br />
Foutmelding: '.$e->getMessage().'
</p>';
trigger_error($sMsg);
}
What am I doing wrong or what can I do so I can select the ID and QUANTITY from database?

Answer 1

The serialization/deserialization part looks fine to me, but the $oStmt->fetchALL( I think should be $oStmt->fetch(, and in foreach($id as $id => $quantity) { use another variable to hold the key instead of id, like foreach($id as $key => $quantity) {.
Also, you don't echo the quantity anywhere. Change echo $id.', '; to echo $key.' '.$quantity; or something and tell us what the output is so we can help further.
