Enable / disable automatic serialization
it can be used to save directly datas which aren't strings (but it's slower)
Directory where to put the cache files (make sure to add a trailing slash)
Enable / disable caching
(can be very usefull for the debug of cached scripts)
File name (with path)
Enable / disable fileLocking
(can avoid cache corruption under bad circumstances)
File Name protection
if set to true, you can use any cache id or group name if set to false, it can be faster but cache ids and group names will be used directly in cache file names so be carefull with special characters...
Current cache group
Current cache id
Cache lifetime (in seconds)
Enable / Disable "Memory Caching"
NB : There is no lifetime for memory caching !
Memory caching array
Memory caching counter
Memory caching limit
Enable / Disable "Only Memory Caching" (be carefull, memory caching is "beta quality")
Pear error mode (when raiseError is called)
(see PEAR doc)
Enable / disable read control
If enabled, a control key is embeded in cache file and this key is compared with the one calculated after the reading.
Type of read control (only if read control is enabled)
Available values are : 'md5' for a md5 hash control (best but slowest) 'crc32' for a crc32 hash control (lightly less safe but faster, better choice) 'strlen' for a length only test (fastest)
Timestamp of the last valid cache
Enable / disable write control (the cache is read just after writing to detect corrupt entries)
Enable write control will lightly slow the cache writing but not the cache reading Write control can detect some corrupt cache files but maybe it's not a perfect control
Constructor
$options is an assoc. Available options are : $options = array( 'cacheDir' => directory where to put the cache files (string), 'caching' => enable / disable caching (boolean), 'lifeTime' => cache lifetime in seconds (int), 'fileLocking' => enable / disable fileLocking (boolean), 'writeControl' => enable / disable write control (boolean), 'readControl' => enable / disable read control (boolean), 'readControlType' => type of read control 'crc32', 'md5', 'strlen' (string), 'pearErrorMode' => pear error mode (when raiseError is called) (cf PEAR doc) (int), 'memoryCaching' => enable / disable memory caching (boolean), 'onlyMemoryCaching' => enable / disable only memory caching (boolean), 'memoryCachingLimit' => max nbr of records to store into memory caching (int), 'fileNameProtection' => enable / disable automatic file name protection (boolean), 'automaticSerialization' => enable / disable automatic serialization (boolean) );
Clean the cache
if no group is specified all cache files will be destroyed else only cache files of the specified group will be destroyed
Test if a cache is available and (if yes) return it
Return the cache last modification time
BE CAREFUL : THIS METHOD IS FOR HACKING ONLY !
Trigger a PEAR error
To improve performances, the PEAR.php file is included dynamically. The file is so included only when an error is triggered. So, in most cases, the file isn't included and perfs are much better.
Remove a cache file
Save some data in a cache file
Set a new life time
Set to debug mode
When an error is found, the script will stop and the message will be displayed (in debug mode only).
Make a control key with the string containing datas
Read the cache file and return the content
Make a file name (with path)
Write the given data in the cache file
Write the given data in the cache file and control it just after to avoir corrupted cache entries
