Zend Data Cache - PHP API
Table of Contents
- Zend Data Cache functions
- zend_shm_cache_store
- Stores a variable identified by key into the cache. If a namespace
is provided, the key is stored under that namespace. Identical
keys can exist under different namespaces
- zend_disk_cache_store
- Stores a variable identified by a key into the cache. If a namespace
is provided, the key is stored under that namespace. Identical
keys can exist under different namespaces
- zend_shm_cache_fetch
- Fetches data from the cache. The key can be prefixed with a
namespace to indicate searching within the specified namespace
only. If a namespace is not provided, the Data Cache searches
for the key in the global namespace
- zend_disk_cache_fetch
- Fetches data from the cache. The key can be prefixed with a
namespace to indicate searching within the specified namespace
only. If a namespace is not provided, the Data Cache searches
for the key in the global namespace
- zend_shm_cache_delete
- Finds and deletes an entry from the cache, using a key to identify
it. The key can be prefixed with a namespace to indicate that
the key can be deleted within that namespace only. If a namespace
is not provided, the Data Cache searches for the key in the global
namespace
- zend_disk_cache_delete
- Finds and deletes an entry from the cache, using a key to identify
it. The key can be prefixed with a namespace to indicate that
the key can be deleted within that namespace only. If a namespace
is not provided, the Data Cache searches for the key in the global
namespace
- zend_shm_cache_clear
- Deletes all entries from all namespaces in the cache, if a 'namespace'
is provided, only the entries in that namespace are deleted
- zend_disk_cache_clear
- Deletes all entries from all namespaces in the cache, if a 'namespace'
is provided, only the entries in that namespace are deleted
PHP Functions
zend_shm_cache_store
Stores a variable identified by key into the cache. If a namespace
is provided, the key is stored under that namespace. Identical keys
can exist under different namespaces
Available since version 4.0
Description
boolean zend_shm_cache_store
(string $key, mixed $value
[ , int $ttl = 0 ])
Parameters
- key
- The data's key. Optional: prefix with a [namespace::]
- value
- Any PHP object that can be serialized
- ttl
- - Time to live, in seconds. The Data Cache keeps an object
in the cache as long as the TTL is not expired. Once the TTL is
expired, the object is removed from the cache. The default value
is 0
Return Value
FALSE if cache storing fails, TRUE otherwise
zend_disk_cache_store
Stores a variable identified by a key into the cache. If a namespace
is provided, the key is stored under that namespace. Identical keys
can exist under different namespaces

(string $key, mixed $value
[ , int $ttl = 0 ])
Parameters
- key
- The data key. Optional: prefix with a namespace
- value
- Any PHP object that can be serialized.

(mixed $key)
Parameters
- key
- The data key or an array of data keys. Optional for key's name:
prefix with a namespace
Return Value
FALSE if no data that matches the key is found, else it returns
the stored data, If an array of keys is given, then an array which
its keys are the original keys and the values are the corresponding
stored data values
zend_disk_cache_fetch
Fetches data from the cache. The key can be prefixed with a namespace
to indicate searching within the specified namespace only. If a namespace
is not provided, the Data Cache searches for the key in the global
namespace
Available since version 4.0
Description
mixed zend_disk_cache_fetch
(mixed $key)
Parameters
- key
- The data key or an array of data keys. Optional for key's name:

zend_shm_cache_delete
Finds and deletes an entry from the cache, using a key to identify
it. The key can be prefixed with a namespace to indicate that the
