 memcached_get() is used to fetch an individual value from the server. You

 to each function call. In the future there will be an option to allow this
 to be an array.
 
+memcached_mget_execute() and memcached_mget_execute_by_key() is
+similar to memcached_mget(), but it may trigger the supplied callbacks
+with result sets while sending out the queries. If you try to perform
+a really large multiget with memcached_mget() you may encounter a
+deadlock in the OS kernel (we fail to write data to the socket because
+the input buffer is full). memcached_mget_execute() solves this
+problem by processing some of the results before continuing sending
+out requests. Please note that this function is only available in the
+binary protocol.

 memcached_get_by_key() and memcached_mget_by_key() behave in a similar nature
 as memcached_get() and memcached_mget(). The difference is that they take
 a master key that is used for determining which server an object was stored
