title: PHP -JavaScript : Monitor changes of a file
body: <p>I'm still new to PHP/Javascript.I've made a simple Clock program in Javascript successfully.</p>
  
  <p>Now i have a file ( and the file will change its content automatically). For example, maybe st like this:
  "12h15: eat breakfast"</p>
  
  <p>And at 13.00, the file's content will change to : "13h:go to the university" </p>
  
  <p>And i wanna make a php( or javascript) code and show up that content every time the file changes.</p>
