wincache_refresh_if_changed - Refreshes the cache entries for the cached files

SYNOPSIS
       bool wincache_refresh_if_changed ([array  $files = NULL])

DESCRIPTION
	Refreshes  the	cache entries for the files, whose names were passed in the input argument. If no argument is specified then refreshes all
       the entries in the cache.

PARAMETERS
	      o $files
		- An array of file names for files that need to be refreshed. An absolute or relative file paths can be used.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

EXAMPLES
	WinCache performs regular checks on the cached files to ensure that if any file has changed then the corresponding entry in the  cache	is
       updated.  By  default this check is performed every 30 seconds. If, for example, a PHP script updates another PHP script where the applica-
       tion's configuration settings are stored, then it may happen that after the configuration settings have been saved to a file, the  applica-
       tion  is  still	using  old  settings for some time until the cache is refreshed. In those cases it may be preferrable to refresh the cache
       right after the file has been changed. The following example shows how this can be done.

       Example #1

	      A wincache_refresh_if_changed(3) example

	      <?php
	      $filename = 'C:inetpubwwwrootconfig.php';
	      $handle = fopen($filename, 'w+');
	      if ($handle === FALSE) die('Failed to open file '.$filename.' for writing');
	      fwrite($handle, '<?php $setting=something; ?>');
	      fclose($handle);
	      wincache_refresh_if_changed(array($filename));
	      ?>
