+
+
+ 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.).
