If the parameters for statement 1 and 2 are identical, do I need to re-bind, or can I do this?
$stmt = $dbh->prepare("SELECT ... thing = :thing ...");
$stmt->bindParam(':thing',$thing);
$stmt->execute();
// do something with data
$stmt = $dbh->prepare("SELECT something else ... thing = :thing ...");
$stmt->execute();
?
Assuming you actually mean:
$stmt = $dbh->prepare("SELECT ... thing = :thing ...");
// ...
No , you are assigning $stmt
to a new PDOStatement
object, which does not hold the information that was stored in the old object.
