Cron is a standard tool available in all Linux/Unix distributions for scheduling tasks that must be executed regularly.

This package provides a full implementation of the Cron tool that works under any platform supported by PHP that has the pcntl_extension.

It manages the execution of scheduled PHP scripts instead of running regular executable programs like the original cron tool.

PHP scripts are executed using forked processes to allow the execution of multiple scheduled scripts at the same time.

Detailed description

This package can be used to schedule the execution of task like the cron program.

First it starts a daemon process using Luca Mariano's PHP fork class to make the cron daemon script run like a standalone program.

It can parse a crontab file with Mick Sear's cron parser class and extract the job scheduling definitions into a MySQL database table.

When it is time to run a scheduled job, it executes the job command in the crontab definition as PHP code as a separate process.

The output of the job PHP code is also stored in a database table.
