wincache_ucache_set - Adds a variable in user cache and overwrites a variable if it already exists in the cache
Code Examples

wincache_ucache_set( mixed$key, mixed$value, [int$ttl = 0] ): bool
boolwincache_ucache_set arrayvalues mixedunusedNULL intttl0



Store the variable using this key name. If a variable with same key is already present the function will overwrite the previous value with the new one. key is case sensitive. key can also take array of name => value pairs where names will be used as keys. This can be used to add multiple values in the cache in one operation, thus avoiding race condition.


Value of a variable to store. Value supports all data types except resources, such as file handles. This paramter is ignored if first argument is an array. A general guidance is to pass null as value while using array as key. If value is an object, or an array containing objects, then the objects will be serialized. See __sleep() for details on serializing objects.


Associative array of keys and values.


Time for the variable to live in the cache in seconds. After the value specified in ttl has passed the stored variable will be deleted from the cache. This parameter takes a default value of 0 which means the variable will stay in the cache unless explicitly deleted by using wincache_ucache_delete or wincache_ucache_clear functions.

Return Values

If key is string, the function returns true on success and false on failure.

If key is an array, the function returns:

If all the name => value pairs in the array can be set, function returns an empty array;

If all the name => value pairs in the array cannot be set, function returns false;

If some can be set while others cannot, function returns an array with name=>value pair for which the addition failed in the user cache.
