这是我正在使用的类定义:

当我尝试:

echo number_word('5,452,455.00','Dollar', 'Cent');

我收到了错误

Fatal error: Call to undefined function number_word()

答案 0 :(得分:4)

number_word是一个包含函数number_word的类。

你想做什么

$nw = new number_word();
echo $nw->number_word('5,452,455.00', 'Dollar', 'Cent');

或将该函数声明为static并调用

echo $nw::number_word('5,452,455.00', 'Dollar', 'Cent');

您可能需要阅读有关Classes and objects

的PHP手册

答案 1 :(得分:1)

继Michael Stum之后,您需要将以下内容添加到number_word()方法中。

return $this->val_word;

答案 2 :(得分:0)

您还可以查看__invoke()
