yii\caching\WinCache::exists PHP Method

WinCache Class Documentation Show file Open project: yiisoft/yii2

exists() public method

This can be faster than getting the value from the cache if the data is big. Note that this method does not check whether the dependency associated with the cached data, if there is any, has changed. So a call to [[get]] may return false while exists returns true.

public exists ( mixed $key ) : boolean
$key	mixed	a key identifying the cached value. This can be a simple string or a complex data structure consisting of factors representing the key.
return	boolean	true if a value exists in cache, false if the value is not in the cache or expired.

    public function exists($key)
    {
        $key = $this->buildKey($key);
        return wincache_ucache_exists($key);
    }
