clean (line 188)

Clean some cache records

Available modes are : Zend_Cache::CLEANING_MODE_ALL (default) => remove all cache entries ($tags is not used) Zend_Cache::CLEANING_MODE_OLD => remove too old cache entries ($tags is not used) This mode is not supported in this backend Zend_Cache::CLEANING_MODE_MATCHING_TAG => remove cache entries matching all given tags ($tags can be an array of strings or a single string) This mode is not supported in this backend Zend_Cache::CLEANING_MODE_NOT_MATCHING_TAG => remove cache entries not matching one of the given tags ($tags can be an array of strings or a single string) This mode is not supported in this backend

  • return: true if no problem
  • access: public
boolean clean ([string $mode = Zend_Cache::CLEANING_MODE_ALL], [tags $tags = array()])
  • string $mode: clean mode
  • tags $tags: array $tags array of tags

Implementation of:
Zend_Cache_Backend_Interface::clean()
Clean some cache records
load (line 90)

Test if a cache is available for the given id and (if yes) return it (false else)

  • return: cached data (or false)
  • access: public
string load (string $id, [boolean $doNotTestCacheValidity = false])
  • string $id: cache id
  • boolean $doNotTestCacheValidity: if set to true, the cache validity won't be tested

Implementation of:
Zend_Cache_Backend_Interface::load()
Test if a cache is available for the given id and (if yes) return it (false else)
remove (line 164)

Remove a cache record

  • return: true if no problem
  • access: public
boolean remove (string $id)
  • string $id: cache id

Implementation of:
Zend_Cache_Backend_Interface::remove()
Remove a cache record
save (line 134)

Save some string datas into a cache record

Note : $data is always "string" (serialization is done by the core not by the backend)

  • return: true if no problem
  • access: public
boolean save (string $data, string $id, [array $tags = array()], [int $specificLifetime = false])
  • string $data: data to cache
  • string $id: cache id
  • array $tags: array of strings, the cache record will be tagged by each string entry
  • int $specificLifetime: if != false, set a specific lifetime for this cache record (null => infinite lifetime)

Implementation of:
Zend_Cache_Backend_Interface::save()
Save some string datas into a cache record
test (line 113)

Test if a cache is available or not (for the given id)

  • return: false (a cache is not available) or "last modified" timestamp (int) of the available cache record
  • access: public
mixed test (string $id)
  • string $id: cache id

Implementation of:
Zend_Cache_Backend_Interface::test()
Test if a cache is available or not (for the given id)
