How to get a list of databases?

Question

I was wondering if there\'s a way in PHP to list all available databases by usage of mysqli. The following works smooth in

Answer 1

Similar to Rick's answer, but this is the way to do it if you prefer to use mysqli in object-orientated fashion:

$mysqli = ... // This object is my equivalent of Rick's $link object.

$sql = "SHOW DATABASES";
$result = $mysqli->query($sql);
if ($result === false) {
    throw new Exception("Could not execute query: " . $mysqli->error);
}

$db_names = array();
while($row = $result->fetch_array(MYSQLI_NUM)) { // for each row of the resultset
    $db_names[] = $row[0]; // Add db name to $db_names array
}

echo "Database names: " . PHP_EOL . print_r($db_names, TRUE); // display array
