How can the error "SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens" be resolved in a PHP PDO query?
The error "SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens" occurs when the number of placeholders in the SQL query does not match the number of parameters passed to the PDO statement. To resolve this issue, ensure that the number of placeholders in the query matches the number of parameters being bound.
// Example code snippet to resolve the error
$query = "SELECT * FROM users WHERE id = :id AND name = :name";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->execute();
