wincache_ucache_meminfo - Retrieves information about user cache memory usage

SYNOPSIS

       array wincache_ucache_meminfo (void  )

DESCRIPTION

	Retrieves information about memory usage by user cache.

RETURN VALUES

	Array of meta data about user cache memory usage or FALSE on failure

	The array returned by this function contains the following elements:

	      o memory_total - amount of memory in bytes allocated for the user cache

	      o memory_free - amount of free memory in bytes available for the user cache

	      o num_used_blks - number of memory blocks used by the user cache

	      o num_free_blks - number of free memory blocks available for the user cache

	      o memory_overhead - amount of memory in bytes used for the user cache internal structures

EXAMPLES

       Example #1

	      A wincache_ucache_meminfo(3) example

	      <pre>
	      <?php
	      print_r(wincache_ucache_meminfo());
	      ?>
	      </pre>

	      The above example will output:

	      Array
	      (
		  [memory_total] => 5242880
		  [memory_free] => 5215056
		  [num_used_blks] => 6
		  [num_free_blks] => 3
		  [memory_overhead] => 176

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));
	      ?>
