The 'php memcached get' command is commonly used to fetch data that has been stored in the Memcached server. This is typically done in situations where you want to avoid expensive database queries by storing the result of a query in memory and fetching it when required.
Here are some examples of how to use 'php memcached get':
This example connects to a Memcached server running on localhost and tries to get the value associated with 'some_key'. If the value exists, it will print the value; otherwise, it echoes that there's no data for this key.
In this example, we're fetching multiple values at once using 'getMulti'. This function returns an associative array with keys and their corresponding values.
What if the key doesn't exist? If the key does not exist, the 'get' function returns FALSE.
Can I fetch multiple keys at once? Yes, you can use the 'getMulti' function to fetch multiple keys at once.
Does 'get' update the expiration time? No, calling 'get' does not affect the expiration time of the cached item.
