About

I created this library to be able to easily create jobs to enqueue and retrieve in a later time. I use it for tasks that I don't want to block on my PHP requests (like sending an email after an account has been created, which I can send later).

Installation

• 1. Install the package
• 2. Add the bootstrap code

1. Install the package

In your root folder, run this command:

2. Add the bootstrap code

As early as possible, and by making sure the code is ran before add or get jobs in a queue:

Check the examples for a complete list of drivers and type of queue, as well as constants to avoid writting the queue drivers and type by hand.

Examples

• 1. Add a job to a queue
• 2. Get a job from a queue
• 3. Check if there is a job to process from a queue
• 4. Set the queue driver
• 5. Set the queue type

1. Add a job to a queue

In this example, we will add a job to a queue.

If you used the "file" driver, you will see a new default.job file containing your job.

If you want to organize in multiple queue identified by a special name, use the third parameter:

If you use the "file" driver, you will see a new emails.job file named after the name of your queue, and containing your job.

2. Get a job from a queue

In this example, we will get the first job in our queue.

As you can see, you will get an instance of Folded\QueueJob when getting the job quuee.

By default, you retreive jobs from the "default" queue. If you use the "file" driver, the job is taken from the "default.job" queue file.

When a job is taken, it is removed from the queue.

If you need to get a job from a named queue, use the first parameter:

For instance, if you use the "file" driver, this will take the job from the "emails.job" queue file.

3. Check if there is a job to process from a queue

In this example, we will check if there is a job to process from a queue.

By default, this method will check if a job is available from the default queue. if you need to check from a named queue, use the first parameter:

4. Set the queue driver

In this example, we will set the queue driver.

Here is a list of supported queue drivers:

• file

If you do not want to write the queue driver by hand, you can use constants instead:

Here is a list of available constants:

• QUEUE_DRIVER_FILE

5. Set the queue type

In this example, we will set the kind of job retreival.

Here is a list of supported queue types:

• fifo: First In, First Out
• filo: First In, Last Out

If you do not want to write the queue type by hand, you can use constants instead:

• QUEUE_TYPE_FIFO
• QUEUE_TYPE_FILO

So the previous code snippet becomes:
