PHP trying to simply a repetitive script involving rowsets - php

Question

I'm trying to simplify a repetitive script that I'm doing in PHP. I've looked at a few loop options but since it involves rowsets being returned from a MySQL stored procedure it's not acting properly. I'm doing this same script about 15 times to return all the data. Ultimately I'm looking to pass back a json_encode array to the ajax calling it. The results I keep getting when trying to put it in a loop is a 500 error or a poorly constructed array.
$stmt->execute();
$values = array();
$stmt->execute();
$values = array();
$rowCount = $stmt->rowCount();
if ($rowCount > 0) {
$row = $stmt->fetchAll(PDO::FETCH_NUM);
$values = array();
foreach ($row as $rowvalue) {
$values[] = array($rowvalue[0], $rowvalue[1], $rowvalue[2], $rowvalue[3], $rowvalue[4], $rowvalue[5]);
}
$stmt -> nextRowset();
$row = $stmt->fetchAll();
foreach ($row as $rowvalue) {
$values[] = array($rowvalue[0], $rowvalue[1], $rowvalue[2], $rowvalue[3], $rowvalue[4], $rowvalue[5]);
}
$stmt -> nextRowset();
$row = $stmt->fetchAll();
foreach ($row as $rowvalue) {
$values[] = array($rowvalue[0], $rowvalue[1], $rowvalue[2], $rowvalue[3], $rowvalue[4], $rowvalue[5]);
}
...
echo json_encode($values);
}
Updated to use the code example below:
$sql = 'CALL fo_SELECT_Operations_Detail(?,?,?)';
$facility = $_POST['facility'];
$startweek = $_POST['startweek'];
$endweek = $_POST['endweek'];
$sql->bindParam(1, $facility, PDO::PARAM_STR);
$sql->bindParam(2, $startweek, PDO::PARAM_STR);
$sql->bindParam(3, $endweek, PDO::PARAM_STR);
$stmt = $conn->query($sql);
$values = array();
do {
$rows = $stmt->fetchAll(PDO::FETCH_NUM);
foreach ($rows as $r) {
$values[] = array($r[0], $r[1], $r[2], $r[3], $r[4], $r[5]);
}
} while ($stmt->nextRowset());
// all processed so now send JSON
echo json_encode($values);

We all forget that SP's which create rowsets also create an annoying empty one as well that has to be Next'd over, but not actually unloaded. The && $stmt->columnCount() looks after getting nextRowset() called but not actually attempting to process it in any way.
$sql = 'CALL fo_SELECT_Operations_Detail(?,?,?)';
$stmt->prepare($sql);
$stmt->bindParam(1, $_POST['facility'], PDO::PARAM_STR);
$stmt->bindParam(2, $_POST['startweek'], PDO::PARAM_STR);
$stmt->bindParam(3, $_POST['endweek'], PDO::PARAM_STR);
$stmt = $conn->execute();
$values = array();
do {
$rows = $stmt->fetchAll(PDO::FETCH_NUM);
foreach ($rows as $r) {
$values[] = [$r[0], $r[1], $r[2], $r[3], $r[4], $r[5]];
}
} while ($stmt->nextRowset() && $stmt->columnCount());
// all processed so now send JSON
echo json_encode($values);
