$cache→saveFor()

Same as save() except with namespace

Namespace is useful to avoid cache name collisions. The ProcessWire core commonly uses cache namespace to bind cache values to the object class, which often make a good namespace.

Example

// save cache using manually specified namespace
$cache->save("my-namespace", "my-cache-name", $value);

// save cache using namespace of current object
$cache->save($this, "my-cache-name", $value);

Usage

// basic usage
$bool = $cache->saveFor($ns, string $name, $data);

// usage with all arguments
$bool = $cache->saveFor($ns, string $name, $data, $expire = 86400);
