Note Submitter: Greg Magarshak ---- Be aware: If you pass a relative path to file_exists, it will return false unless the path happens to be relative to the "current PHP dir" (see chdir() ). Here is a function I wrote to get the real path of a relative filename. You can use this in place of file_exists. <?php /** * Check if a file exists in the include path * And if it does, return the absolute path. * @param string $filename * Name of the file to look for * @return string|false * The absolute path if file exists, false if it does not */ function realPath ($filename) { // Check for absolute path if (realpath($filename) == $filename) { return $filename; } // Otherwise, treat as relative path $paths = explode(PS, get_include_path()); foreach ($paths as $path) { if (substr($path, -1) == DS) { $fullpath = $path.$filename; } else { $fullpath = $path.DS.$filename; } if (file_exists($fullpath)) { return $fullpath; } } return false; } ?>
