 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() 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
