------ Solution --------------------

// Connect $ str = "...";
$ Exp = explode ("\ n", $ str );

// It is difficult to convert the number to a Chinese representation, and it is inefficient. If this function is not affected, you do not need this function.
Function num2str ($ num)
{
$ Cns = array ('0', 'yi', '2', '3', '4', '5', '6', '7 ', '8', '9', '10'
