¿Cómo usar el objeto de retorno PHP PDO en varias ocasiones?
As per my below code $result object does not display any data in while loop.
Mi código
try {
$dbhandle = new PDO("sqlite:".$database);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$result=$dbhandle->query("select * from table");
if($result)
{
$row=$result->fetch(PDO::FETCH_ASSOC)
if(count($row)>0)
{
while ($rs1 = $result->fetch(PDO::FETCH_ASSOC, PDO::FETCH_ORI_NEXT))
{
echo "<pre>";
print_r($rs1);
echo "</pre>";
}
}
else
{
// error message
}
}

This is because the cursor is at the end. So you have to reset the cursor.

Normally in MySQL you can use MySQL Free result.

Although not strictly answering your question, why dont you take a look at the $stmt->fetchAll
with PDO statements which takes care of the loop for you and returns you the full associative arrays? Saves you a ton of time!

Please give me some suggestion or example about closecursor, i am not getting. - Hkachhia
Close cursor does not seem to reset the cursor to the beginning, allowing more fetch statements. A fetchAll followed by a closeCursor and another fetch returns an empty row. - david grenier
