<?php
 $dir = '/var/www/devData/test';

 // create new directory with 777 permissions if it does not exist yet
 // owner will be the user/group the PHP script is run under
 if ( !file_exists($dir) ) {
  mkdir ($dir, 0777);
 }
 if (isset($_POST['data'])) {

         $stringData = $_POST['data'];
         $file = "/var/www/devData/test/ciao.txt"; 
         $fh = fopen($file, 'r+') or die("can't open file");
         fwrite($fh, $stringData);
         $theData = fread($fh, filesize($myFile)); //this is the string that i have to pass
         fclose($fh); 

         echo $theData;  // <-- ECHO

 }


 ?>

You have to OUTPUT the data, not return it. That is, echo it. If the string is not yet json encoded, use echo json_encode($theData);
