title: PHP Phar - file_exists() issue
body: <p>My Phar script creates a new file with fwrite, which works fine, it creates the new file outside the phar, in the same directory as the phar file.</p>
  
  <p>But then when i use if(file_exists('file.php')) it doesn't pick it up.</p>
  
  <p>But then include and require do pick it up. </p>
  
  <p>Anyone know about this problem?
  Been testing and researching for a while a can't seem to find a solution.</p>
