Can we use Named parameters in SQL queries with amphp\mysql package?

[Raghu Veer Dendukuri]

While I am able to use question marks in prepared statements, I am getting error when I try to use named parameters when making insert query

my code using question marks (worked):

$sql = "INSERT INTO site_members (lastname, firstname) VALUES (?, ?)";
$statement = yield $pool->prepare($sql);
$result = yield $statement->execute(['Doe', 'John']);
$id = $result->getLastInsertId();
echo "id: " . $id . "\n";

code with named parameters:

$array = array(':lastname' => 'Doe', ':firstname' => 'John');
				
$sql = "INSERT INTO site_members (lastname, firstname) VALUES (:lastname, :firstname)";
$statement = yield $pool->prepare($sql);
$result = yield $statement->execute($array);
$id = $result->getLastInsertId();
echo "id: " . $id . "\n";

when I try using named parameters, as shared in the above, I get the following error:

PHP Fatal error:  Uncaught Error: Named parameter 'lastname' missing for executing prepared statement in /home/user/public_html/vendor/amphp/mysql/src/ConnectionStatement.php:124

The issue you're facing appears, because you're prefixing your array of parameters with a colon, so use $array = array('lastname' => 'Doe', 'firstname' => 'John'); instead of $array = array(':lastname' => 'Doe', ':firstname' => 'John');.
