wincache_fcache_meminfo - Retrieves information about file cache memory usage

SYNOPSIS

       array wincache_fcache_meminfo (void  )

DESCRIPTION

	Retrieves information about memory usage by file cache.

RETURN VALUES

	Array of meta data about file 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 file cache

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

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

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

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

EXAMPLES

       Example #1

	      A wincache_fcache_meminfo(3) example

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

	      The above example will output:

	      Array
	      (
		  [memory_total] => 134217728
		  [memory_free] => 131339120
		  [num_used_blks] => 361
		  [num_free_blks] => 3
		  [memory_overhead] => 5856
	      )

apc_cache_info - Retrieves cached information from APC's data store

SYNOPSIS

       array apc_cache_info ([string  $cache_type = ""], [bool	$limited = false])

DESCRIPTION

	Retrieves cached information and meta-data from APC's data store.

PARAMETERS

	      o $cache_type
		-  If $cache_type is " user", information about the user cache will be returned.  If $cache_type is " filehits", information about
		which files have been served from the bytecode cache for the current request will be returned. This feature  must  be  enabled	at
		compile  time  using  --enable-filehits.  If an invalid or no $cache_type is specified, information about the system cache (cached
		files) will be returned.

	      o $limited
		- If $limited is TRUE, the return value will exclude the individual list of cache entries. This is useful when trying to  optimize
		calls for statistics gathering.

RETURN VALUES

	Array of cached data (and meta-data) or FALSE on failure

       Note

	      apc_cache_info(3) will raise a warning if it is unable to retrieve APC cache data. This typically occurs when APC is not enabled.
