Question

I know this question has been asked before, but I tried eveything and can’t find how it works.
I have a prepared query, and I need to use it twice with two while() loops like this:

$query = $pdo->prepare('SELECT ...');
$query->execute();
while( $results = $query->fetch() ){
 // instructions
}

// rewind
while( $results = $query->fetch() ){
 // instructions
}

Thanks

Answer 1

Could be as simple as getting all the results on the 1st iteration and loop on the 2nd:

$res = array();
while( $results = $query->fetch() ){
   $res[] = $results;
   // instructions
}

foreach($res as $results){
   // instructions
}
