title: How do I send some alert or msg to another php file
body: <p>I have two php files...</p>
  <p>PHP_File2 is a file which receives some data with post methods...and then it writes that data to some file and performs some operation</p>
  <p>PHP_File1 is the file where I want to show the data in some input box or to some other text tags as soon as data is received to PHP_File2, without refreshing PHP_File1 or without reloading it...
