    Why don’t you define the variable type of the function here? Who knows if it is an integer or a character? -PHP Chinese website Q&A-Why don't you define the variable type of the function here? Who knows whether it is an integer or a character? -PHP Chinese website Q&A

    PHP不用像其他一样的明确变量类型,只要定义了就行。
