4 min readTo find the keys that are being evicted from Memcache, you can use the "stats items" command in the Memcache command line interface. This command will display a list of all the items that are currently stored in the Memcache server, along with their expiration time and eviction status. By monitoring this list, you can identify which keys are being evicted and take appropriate action, such as increasing the memory limit or optimizing your cache usage.

4 min readTo store different values with the same key in Memcache, you can serialize the values into a single data structure before storing them. This can be done by using a data structure such as a dictionary or a list that maps the different values to unique identifiers within the key. When retrieving the values, you can deserialize the data structure and access the values based on their identifiers. This allows you to store multiple values with the same key in Memcache and retrieve them as needed.
-
5 min readTo add a prefix to memcache keys, you can include the prefix as part of the key name when setting or getting values in the memcache instance. Simply append the desired prefix string to the key name before storing it in memcache. This will help organize and differentiate your keys within the memcache instance, making it easier to manage and retrieve them when needed.

4 min readTo allow many IP addresses to connect to a Memcache server, you can configure the Memcache server settings to allow connections from multiple IPs. This can typically be done by editing the Memcache configuration file and adding the IP addresses that you want to allow to connect to the server.You may need to restart the Memcache server after making these changes for them to take effect.
-
5 min readTo expire cached data in Memcache, you can simply set a time-to-live (TTL) value for each key when setting the data in the cache. This TTL value determines how long the data will remain in the cache before it expires and is automatically removed.Alternatively, you can manually delete specific cached data by using the delete or flush method provided by the Memcache client library you are using.

6 min readTo use memcached with PHP, you first need to install the memcached server on your server. You can do this using package management tools like apt-get or yum.Once memcached is installed, you need to install the PHP memcached extension. This can be done using PECL, by running the command "pecl install memcached". After installing the extension, you need to enable it in your php.ini file by adding the line "extension=memcached.so".

6 min readTo install memcache in MAMP, you will need to download the Memcached PHP extension from http://pecl.php.net/package/memcache and compile it with MAMP's PHP version. Once you have downloaded the extension, you will need to extract it and navigate to the folder using your command line. From there, you can run the following commands: "phpize", "./configure", "make", and "make install" to compile and install the extension.
-
5 min readTo remove specific keys in Memcache, you can use the delete() function provided by the Memcache client library. This function takes the key of the data that you want to remove as its parameter. You can specify the key or keys you want to remove from the cache by passing them as arguments to the delete() function. This will delete the corresponding data from the cache and free up memory space. It is important to note that once a key is deleted from the cache, it cannot be retrieved again.

5 min readTo configure CakePHP to use Memcached, you will first need to install the Memcached extension on your server. Once the extension is installed, you can then configure CakePHP to use Memcached by updating the app.php configuration file.In the app.php file, you will need to specify the Cache configuration to use Memcached as the caching engine. You can do this by setting the 'className' key to 'Memcached' in the Cache configuration.

4 min readTo store a value greater than 1MB via memcached, you can first compress the data to reduce its size. Once compressed, you can divide the data into smaller chunks and store each chunk individually with a unique key. This way, you can retrieve and reconstruct the original value by fetching and concatenating all the chunks with the respective keys. This approach allows you to effectively store and retrieve large values in memcached while staying within its size limitations.

7 min readBuilding a Svelte component library involves creating reusable components that can be easily imported and used in different projects. To get started, you first need to decide on the components you want to include in your library and organize them into separate Svelte files.Next, you can create a new Svelte project and start building your components. Each component should have its own folder with a .svelte file containing the component code.
