I've been learning Ajax and now I'm wondering how it allows a string from Javascript to be passed to php.
It was said before that the problem with passing Javascript to PHP is that the PHP code gets run first, and then the Javascript gets run. So when Javascript generates a string it's already too late.
Does this mean that Ajax allows PHP code to be run after Javascript?
分享 The php interpreter sitting on the server is basically interprets whatever php script into (usually) HTML page.
That's why you can never "pass" javascript variable into php as to the interpreter, your javascript is just yet another string, without any special meaning. Your javascript is run by your browser and doesn't even aware that it was being produced by PHP.
I believe that's what it means by "too late".
