在PHP数组中的1个键中添加两个值？

Question

如何在用{分隔的':ID'中添加两个值。值是数字，我希望':ID'像1.2,2.3等......

 $pdoExec = $stmt->execute(array(
                    ':username' => $_SESSION['username'],
                    ':ID' => $_SESSION['memberID'] "." $row['#'],
        ) );

Answer 1

使用floatval函数将字符串转换为浮点值：

$pdoExec = $stmt->execute(array(
                    ':username' => $_SESSION['username'],
                    ':ID' => floatval($_SESSION['memberID']. "." .$row['#']),
        ) );
