title: Fastest way possible to read contents of a file
body: <p>Ok, I'm looking for the fastest possible way to read all of the contents of a file via php with a filepath on the server, also these files can be huge.  So it's very important that it does a READ ONLY to it as fast as possible.</p>
  
  <p>Is reading it line by line faster than reading the entire contents?  Though, I remember reading up on this some, that reading the entire contents can produce errors for huge files.  Is this true?</p>
