Why use php_crontab?

When we have a handful of crontab tasks, crontab service is enough for us to manage them. If we have many crontab tasks, there will be some problems like:

• The crontab tasks are managed in a text file. If there are no comment, it will be hard for fresh man to understand what they are.
• If the crontab tasks are distributed in different servers, it will be hard to manage them.
• If you want to collect the crontab tasks' logs, it will be not easy.
• Tasks of different users must written in different files. Based on the above reasons, we need a crontab manager which can manage crontab tasks together and configure the tasks.

How to use php_crontab?

First composer require jenner/crontab.
There are two ways to use php_crontab to manage your crontab tasks. You can just write a php script and add it to the crontab config file with the command crontab -e. The php script should run every minute. For example tests/simple.php
Or you can write a php daemon script which will run as a service and will not exit until someone kill it. It will check the tasks every minute. For example tests/daemon.php
