GearmanWorker::addServer

If you suddenly start getting a:

PHP Fatal error:  Uncaught exception 'GearmanException' with message 'Failed to set exception option' in

...on your GearmanWorker::work() calls, I was able to fix this by specifying values to GearmanWorker::addServer(), even if they are the same as the documented default values.

Crashes:

<?php
$gmw = new GearmanWorker();
$gmw->addServer();
$gmw->work();
?>

Works:

<?php
$gmw = new GearmanWorker();
$gmw->addServer("127.0.0.1", 4730);
$gmw->work();
?>

Go figure. :)

To properly test the server added you could use the following code:<?php// create the worker$worker= new GearmanWorker();// add the  job server (bad host/port)$worker->addServer('127.0.0.2', 4731);// define a variable to hold application data$count = 0;// add the reverse function$worker->addFunction('reverse', 'my_reverse_function', $count);// test job server responseif (!@$worker->echo('test data')) {    die($worker->error());}// start the worker listening for job submissionswhile ($worker->work());function my_reverse_function($job, &$count){    $count++;    return $count . ': ' . strrev($job->workload()) . "\n";}?>

I was receving following message on add server Uncaught exception 'GearmanException' with message 'Failed to set exception option' in <<filename>>:<<linenumber >> was on centos 6.5fixed by following steps:yum install gearmand/etc/init.d/gearmand start

PHP Fatal error:  Uncaught exception 'GearmanException' with message 'Failed to set exception option'also indicates the gearmand daemon is not running.

The manual states that you get a TRUE on success and FALSE on failure. When I have attempted to connect to a server that is powered off I still get TRUE. The return from returnCode() is 0 which is the same as the returnCode() from a successful connection.I have not yet found a way around this.

On Ubuntu (php7 php-gearman/xenial,now 2.0.2+1.1.2-1+deb.sury.org~xenial+1 amd64) this function throws a GearmanException. Please use in try catch

No socket I/O happens in addserver.
