GearmanWorker::addFunction — Register and add callback function
说明
public GearmanWorker::addFunction
( string $function_name
, callable $function
[, mixed &$context
[, int $timeout
]] ) : bool
Registers a function name with the job server and specifies a callback corresponding to that function. Optionally specify extra application context data to be used when the callback is called and a timeout.
参数
function_name- The name of a function to register with the job server
function- A callback that gets called when a job for the registered function name is submitted
context- A reference to arbitrary application context data that can be modified by the worker function
timeout- An interval of time in seconds
返回值
成功时返回 true， 或者在失败时返回 false。
范例
Example #1 Simple worker making use of extra application context data
<?php# get a gearman worker$worker= new GearmanWorker(); # add the default server (localhost)$worker->addServer(); # define a variable to hold application data$count= 0; # add the "reverse" function$worker->addFunction("reverse", "reverse_cb", $count);# start the workerwhile ($worker->work());function reverse_cb($job, &$count) { $count++; return "$count: " . strrev($job->workload()); } ?>
Running a client that submits two jobs for the reverse function would have output similar to the following:
1: olleh 2: dlrow
