Laravel: Serialization of ‚Closure‘ is not allowed with Jobs and Queues

Posted on 26. Februar 2018 Comments

When dispatching Jobs onto a queue it’s possible to get the following error:

Serialization of ‚Closure‘ is not allowed

This basically means that you are either passing a class that contains anonymous functions („closures“ in PHP) or that in the Job itself there is an anonymous function. This could also be a library you are using. PHP is unable to serialize closures per se. When Jobs get dispatched onto the queue, everything has to be serialized before. If you absolutely must use them this way, look into the Super Closure package by jeremeamia. However, just rewriting the code a little might be easier:

 

Solution

Instead of passing a whole object to the Job like so:

$objOfClassWithClosures = ...;
$job = new Job($objOfClassWithClosures);
dispatch($job);

Pass the Fully Qualified Class Name (that’s what ClassName::class returns) to the job and instantiate the object on the other side, possibly even using Laravels Container:

$job = new Job(ClassWithClosures::class);
dispatch($job);

Inside the job you can then use the constructor to make a new instance of that class:

public function __construct(string $fqcn) {
$objOfClassWithClosures = app()->make($fqcn);
}

PHP Commandline Notification

Posted on 3. Januar 2018 Comments

When you run long (PHP) jobs it’s easy to forget about the terminal. That’s why I’ve created a small PHP package that will make a little sound. Because PHP itself doesn’t have this functionality anymore it’s possible to just echo the ASCII sign for BEL. Simply put this at the end of your PHP job:

use repat\CommandlineBell;
// flashes screen if possible, otherwise just bell()
CommandlineBell::flash();
// makes a beep sound
CommandlineBell::bell();

Under the hood it’s really just:
echo "0x07";

A good (non-PHP) alternative I found is brb by Viktor Fröberg, just run commands like this

php artisan migrate --seed ; brb

Of course it’s always possible to just run a TTS app on the commandline via exec() like this:

exec("say terminal task done");

Or you could do it similar to brb:

php artisan migrate --seed ; say seeding done
