$myParams = Array ();

$myParams [' level '] = "warn";

$myParams [' content '] = "It s a test";

$client = new Gearmanclient ();

If the Gearman does not respond within 300 milliseconds, close the connection directly

$client->settimeout (300);

$client->addserver ("121.111.111.111", "4730");

$client->dobackground ("Log", Json_encode ($myParams));

3.Server

$worker = new Gearmanworker ();

$worker-Addserver ("112.111.111.111", "4730");

$worker-AddFunction ("Log", "Dolog");

while ($worker, work ());

function Dolog ($job) {

Global $logger, $logLevels, $myParams;

$myParams = NULL;

$myParams = Json_decode ($job, workload ());

$level = $myParams->level;

if (!in_array ($level, $logLevels)) $level = ' info ';

$logger-$level ($myParams->content);

}
