Aerospike::prepend - prepends a string to the string value in a bin
public int Aerospike::prepend ( array $key, string $bin, string $value [, array $options ] )

key the key under which the bin can be found. An array with keys ['ns','set','key'] or ['ns','set','digest'].
bin the name of the bin in which we have a numeric value.
