Constants

DELIMITER	Text lines are always terminated by \r\n. Unstructured data is also terminated by \r\n, even though \r, \n or any other 8-bit characters may also appear inside the data. Therefore, when a client retrieves data from a server, it must use the length of the data block (which it will be provided with) to determine where the data block ends, and not the fact that \r\n follows the end of the data block, even though it does.
ERROR	"ERROR\r\n" means the client sent a nonexistent command name.
CLIENT_ERROR	"CLIENT_ERROR \r\n" means some sort of client error in the input line, i.e. the input doesn't conform to the protocol in some way. is a human-readable error string.
SERVER_ERROR	"SERVER_ERROR \r\n" means some sort of server error prevents the server from carrying out the command. is a human-readable error string. In cases of severe server errors, which make it impossible to continue serving the client (this shouldn't normally happen), the server will close the connection after sending the error line. This is the only case in which the server closes a connection to a client.
STORED	"STORED\r\n", to indicate success.
NOT_STORED	"NOT_STORED\r\n" to indicate the data was not stored, but not because of an error. This normally means that the condition for an "add" or a "replace" command wasn't met.
EXISTS	"EXISTS\r\n" to indicate that the item you are trying to store with a "cas" command has been modified since you last fetched it.
NOT_FOUND	"NOT_FOUND\r\n" to indicate that the item you are trying to store with a "cas" command did not exist.
TOUCHED	"TOUCHED\r\n" to indicate success
DELETED	"DELETED\r\n" to indicate success
VERSION	Antwort und Befehl; Unterscheidet sich nur im Case Siehe Funktion getVersion()
OK	"OK\r\n" in response (unless "noreply" is given as the last parameter)

sendStorageCommandAndReceive

[noreply]\r\n cas [noreply]\r\n

"set" means "store this data".

"add" means "store this data, but only if the server doesn't already hold data for this key".

"replace" means "store this data, but only if the server does already hold data for this key".

"append" means "add this data to an existing key after existing data".

"prepend" means "add this data to an existing key before existing data".

"noreply" optional parameter instructs the server to not send the reply. NOTE: if the request line is malformed, the server can't parse "noreply" option reliably. In this case it may send the error to the client, and not reading it on the client side will break things. Client should construct only valid requests.

Parameters

string	$command	is "set", "add", "replace", "append" or "prepend"
string	$key
string	$data
integer	$expireTime	null or 0 never expired
integer	$flags
boolean	$noReply
