How to execute another php's file with webix,

Hello,
I want to know how can i execute a php’s file with webix. Indeed, i’ve a php’s file which create a json’s file that i use in my datatable. So how can i make that with possibility in each time to refresh the datatable in orer to recover the new values of json’s file
Thank for your answers

Instead of calling php file that recreates json file, why do not load data from php file directly

Instead of file_put_contents($file, $data); just use echo $data; in the php file and to load data, url:"some.php"

thank you for your answers @maksim.
