请随意使用下面的示例作为您的查询。
// Your sql query
$sql = "SELECT ID, note FROM notes";
// Prepare your statement
$stmt = $db -> prepare($sql);
// Execute your prepared statement
$stmt -> execute();
// Retreive all rows
$notes = $stmt -> fetchAll();
// Check if array is not empty
if (!empty($notes)) {
//Spit out the array
print_r($notes);
}
