One shall note, that callback function MUST either return a valid Gearman status code, or return nothing (do not return).
I.e. these are valid complete callbacks:
<?php
function goodCallbackOne(GearmanTask $task)
{
print_r($task);
}
?>
<?php
function goodCallbackTwo(GearmanTask $task)
{
print_r($task);
return GEARMAN_SUCCESS;
}
?>
While following is NOT, unless you want your client code to fail with Gearman error 'german wait:no active file descriptors':
<?php
function badCallbackTwo(GearmanTask $task)
{
print_r($task);
return true;
}
?>
