如果要将所有PHP函数与jQuery（Ajax）结合使用并获得响应，最好将所有PHP函数放在单独的文件中吗？

Question

I normally put all functions in separate files, but I'm imagining ways to put everything in one file.

You could probably send the name of the needed PHP function along with each ajax-call and write something like the following in the PHP-file:

if($_POST['function_name'] == 'myfunction'){
myfunction();
}

function myfunction()
{
echo 'This to be echoed.'
}

Somehow that feels wrong. So, what is your opinion? All functions in one file or all separated?

Answer 1

If your project is really big and has lots of people engaged to the project, separating files for each functions would be a nice option to work together.

But if it's not the case like that, putting every functions in one file will make your project looks more simple and productive.

Please note that this is just my personal opinion.
