Google Developer Tool. in the network, XHR can see the ajax request address, which contains submitted data and background response information.

Xdebuger

Google F12 is enough. you don't have to worry about using the debugging tool that comes with the framework.

Chrome-> F12 check-> NetWork-> XHR

F12 review elements

You can write the variable to the file, and then run ajax to view the file. tp can directly use log records.

With an extension of xdebug and IDE, you can implement php breakpoint or something.
Next, the next breakpoint. you can Debug php after you break it down !!

Firefox's firebug is not quite good.

File_put_contents ('/log.txt', var_export ($ _ POST, true ));
// The execution of the program will not end at all, and the obtained token will be output to the log.txt file of the current directory.
