title: Does file_get_contents use a cache?
body: <p>I have a function that generates a table with contents from the DB. Some cells have custom HTML which I'm reading in with file_get_contents through a templating system.</p>
  
  <p>The small content is the same but this action is performed maybe 15 times (I have a limit of 15 table rows per page). So does file_get_contents cache if it sees that the content is the same?</p>
