oci_fetch_all equivalent for pdo? - php

Question

I'm trying to get result from a postgres database with the fetchAll() function. But I have to get the same result from an Oracle DB and it doesn't work with the fetchAll() function.
With fetchall() i have an array with index numbers and each array represent a row from the db, but with oci_fetch_all each array have an array with the column name as index, and each array represent a column from the db and that's what I need
Postgres :
$stmt = $db->prepare($req);
$stmt->execute();
$res = $stmt->fetchAll();
output :
array(4) {

This is not possible in PDO. PDO doesn't return results indexed by column names. This behaviour is not very intuitive when writing code, so it's best avoided. Use the normal fetch modes, which order results by rows.
If you need to write some shim for backwards compatibility you can do it yourself with nested loops.
$s = $pdo->query("SELECT * FROM bar");
$allByColumns = [];
foreach ($s->fetchAll(PDO::FETCH_ASSOC) as $index => $row) {
foreach ($row as $column => $value) {
$allByColumns[$column][$index] = $value;
}
}
var_dump($allByColumns);
