预定义常量

下列常量由此扩展定义，且仅在此扩展编译入 PHP 或在运行时动态载入时可用。

Return values. Always check GearmanClient::error() or GearmanWorker() for a string error, as it may contain more details:

GEARMAN_SUCCESS ( integer ): Whatever action was taken was successful.
GEARMAN_IO_WAIT ( integer ): When in non-blocking mode, an event is hit that would have blocked.
GEARMAN_ERRNO ( integer ): A system error. Check GearmanClient::errno() or GearmanWorker::errno() for the system error code that was returned.
GEARMAN_NO_ACTIVE_FDS ( integer ): GearmanClient::wait() or GearmanWorker() was called with no connections.
GEARMAN_UNEXPECTED_PACKET ( integer ): Indicates something going very wrong in gearmand. Applies only to GearmanWorker.
GEARMAN_GETADDRINFO ( integer ): DNS resolution failed (invalid host, port, etc).
GEARMAN_NO_SERVERS ( integer ): Did not call GearmanClient::addServer() before submitting jobs or tasks.
GEARMAN_LOST_CONNECTION ( integer ): Lost a connection during a request.
GEARMAN_MEMORY_ALLOCATION_FAILURE ( integer ): Memory allocation failed (ran out of memory).
GEARMAN_SERVER_ERROR ( integer ): Something went wrong in the Gearman server and it could not handle the request gracefully.
GEARMAN_WORK_DATA ( integer ): Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do() . Sent to update the client with data from a running job. A worker uses this when it needs to send updates, send partial results, or flush data during long running jobs.
GEARMAN_WORK_WARNING ( integer ): Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do() . Updates the client with a warning. The behavior is just like GEARMAN_WORK_DATA , but should be treated as a warning instead of normal response data.
GEARMAN_WORK_STATUS ( integer ): Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do() . Sent to update the status of a long running job. Use GearmanClient::doStatus() to obtain the percentage complete of the task.
GEARMAN_WORK_EXCEPTION ( integer ): Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do() . Indicates that a job failed with a given exception.
GEARMAN_WORK_FAIL ( integer ): Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do() . Indicates that the job failed.
GEARMAN_COULD_NOT_CONNECT ( integer ): Failed to connect to servers.
GEARMAN_INVALID_FUNCTION_NAME ( integer ): Trying to register a function name of NULL or using the callback interface without specifying callbacks.
GEARMAN_INVALID_WORKER_FUNCTION ( integer ): Trying to register a function with a NULL callback function.
GEARMAN_NO_REGISTERED_FUNCTIONS ( integer ): When a worker gets a job for a function it did not register.
GEARMAN_NO_JOBS ( integer ): For a non-blocking worker, when GearmanWorker::work() does not have any active jobs.
GEARMAN_ECHO_DATA_CORRUPTION ( integer ): After GearmanClient::echo() or GearmanWorker::echo() the data returned doesn't match the data sent.
GEARMAN_NEED_WORKLOAD_FN ( integer ): When the client opted to stream the workload of a task, but did not specify a workload callback function.
GEARMAN_PAUSE ( integer ): For the non-blocking client task interface, can be returned from the task callback to "pause" the call and return from GearmanClient::runTasks() . Call GearmanClient::runTasks() again to continue.
GEARMAN_UNKNOWN_STATE ( integer ): Internal client/worker state error.
GEARMAN_SEND_BUFFER_TOO_SMALL ( integer ): Internal error: trying to flush more data in one atomic chunk than is possible due to hard-coded buffer sizes.
GEARMAN_TIMEOUT ( integer ): Hit the timeout limit set by the client/worker.

GearmanClient options:

GEARMAN_CLIENT_GENERATE_UNIQUE ( integer ): Generate a unique id (UUID) for each task.
GEARMAN_CLIENT_NON_BLOCKING ( integer ): Run the cient in a non-blocking mode.
GEARMAN_CLIENT_UNBUFFERED_RESULT ( integer ): Allow the client to read data in chunks rather than have the library buffer the entire data result and pass that back.
GEARMAN_CLIENT_FREE_TASKS ( integer ): Automatically free task objects once they are complete. This is the default setting in this extension to prevent memory leaks.

GearmanWorker options:

GEARMAN_WORKER_NON_BLOCKING ( integer ): Run the worker in non-blocking mode.
GEARMAN_WORKER_GRAB_UNIQ ( integer ): Return the client assigned unique ID in addition to the job handle.

Base Gearman configuration:

GEARMAN_DEFAULT_TCP_HOST ( string )
GEARMAN_DEFAULT_TCP_PORT ( integer )
GEARMAN_DEFAULT_SOCKET_TIMEOUT ( integer )
GEARMAN_DEFAULT_SOCKET_SEND_SIZE ( integer )
GEARMAN_DEFAULT_SOCKET_RECV_SIZE ( integer )
GEARMAN_MAX_ERROR_SIZE ( integer )
GEARMAN_PACKET_HEADER_SIZE ( integer )
GEARMAN_JOB_HANDLE_SIZE ( integer )
GEARMAN_OPTION_SIZE ( integer )
GEARMAN_UNIQUE_SIZE ( integer )
GEARMAN_MAX_COMMAND_ARGS ( integer )
GEARMAN_ARGS_BUFFER_SIZE ( integer )
GEARMAN_SEND_BUFFER_SIZE ( integer )
GEARMAN_RECV_BUFFER_SIZE ( integer )
GEARMAN_WORKER_WAIT_TIMEOUT ( integer )

If you are getting

Error 26 GEARMAN_COULD_NOT_CONNECT (integer)

and you are running SELinux then you need to set

setsetbool -P http_can_network_connect = 1

retrunCodes is missed from No.33 .
I think , Correct retrunCodes are this.

an update (gearman 0.35):

I looked everywhere for for a dump of the values of each of the gearman constants. I ended up in the gearman source.

You'll find this useful if you ever just echo the return code.
