README

F3Scheduler is a simple cron-style task scheduler plugin for the Fat-Free Framework (F3). It allows you to register periodic tasks using cron expressions and execute them via a route or CLI-safe handler.

🚀 Features

• Register tasks using cron expressions or helper methods like everyMinute(), hourly(), daily(), etc.
• Supports callable PHP functions and string commands (executed via php index.php ...).
• Flexible error handling via setErrorHandler(...).
• Built-in route: GET /cron/schedule/run for triggering tasks from CRON.
• Designed for F3 and easy integration.

🛠 Installation

composer require antonchaikin/f3-scheduler

🧩 Setup

In your app bootstrap:

\F3Scheduler\F7SchedulePlugin::register();

This will:

• Register the route GET /cron/schedule/run
• Bind Schedule to $f3->schedule for easy static access

🧪 Usage

Register a task:

$f3->schedule::everyMinute(function () {
    echo "Run every minute!";
});

Register a shell command:

$f3->schedule::daily("clear-cache");

Custom cron:

$f3->schedule::on("0 0 1 * *", fn() => echo "Run every 1st of month!");

Set error handler:

$f3->schedule::setErrorHandler(function ($e) {
    error_log("[SCHEDULE ERROR] " . $e->getMessage());
});

Trigger tasks manually (e.g. from cron job):

curl https://your-app.com/cron/schedule/run

⏰ System Cron Setup

To run scheduled tasks every minute, add the following line to your server's crontab:

* * * * * curl -s https://your-app.com/cron/schedule/run > /dev/null 2>&1

Make sure the route /cron/schedule/run is publicly accessible or secured via IP/user-agent as needed.

📚 Available Methods

• everyMinute(callable|string)
• everyFiveMinute(callable|string)
• everyTenMinutes(callable|string)
• everyFifteenMinutes(callable|string)
• everyThirtyMinutes(callable|string)
• hourly(callable|string)
• daily(callable|string)
• dailyNoon(callable|string)
• weekly(callable|string)

🧠 Notes
