apc_add Cache a new variable in the data store &reftitle.description; boolapc_add stringkey mixedvar intttl0 arrayapc_add arrayvalues mixedunusedNULL intttl0 Caches a variable in the data store, only if it's not already stored. Unlike many other mechanisms in PHP, variables stored using apc_add will persist between requests (until the value is removed from the cache). &reftitle.parameters; key Store the variable using this name. keys are cache-unique, so attempting to use apc_add to store data with a key that already exists will not overwrite the existing data, and will instead return &false;. (This is the only difference between apc_add and apc_store.) var The variable to store ttl Time To Live; store var in the cache for ttl seconds. After the ttl has passed, the stored variable will be expunged from the cache (on the next request). If no ttl is supplied (or if the ttl is 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.). values Names in key, variables in value. &reftitle.returnvalues; Returns TRUE if something has effectively been added into the cache, FALSE otherwise. Second syntax returns array with error keys. &reftitle.examples; ]]> &example.outputs; &reftitle.seealso; apc_store apc_fetch apc_delete
