title: Can PHP 5.5.5 load Phar files from OPcache?
body: <p>The version of PHP in use is 5.5.5 and I know this version of PHP can store precompiled script bytecode in shared memory, as mentioned in the following page:
  <a href="http://php.net/manual/en/intro.opcache.php" rel="nofollow">http://php.net/manual/en/intro.opcache.php</a></p>
  
  <p>I also know OPcache can compile files as mentioned in the following page:
  <a href="http://php.net/manual/en/function.opcache-compile-file.php" rel="nofollow">http://php.net/manual/en/function.opcache-compile-file.php</a></p>
  
  <p>Which would be great if this worked with Phar files. However, I can't tell whether PHP is loading my Phar files from bytecode in shared memory or not. I can't use the opcache_is_script_cached function to test because this is not available in PHP 5.5.5, the function is only available in PHP 5.6 and newer.</p>
  
  <p>Could someone please clarify if this works or not, or at least explain to me how I can find out?</p>
