This is the XP Framework's development checkout.

If you just want to use the XP Framework, grab a release using composer require xp-framework/core. If you wish to use this development checkout, clone this repository instead.

The entry point for software written in the XP Framework is not the PHP interpreter's CLI / web server API but either a command line runner or a specialized web entry point. These runners can be installed by using the following one-liner:

$ cd ~/bin
$ curl -sSL https://bintray.com/artifact/download/xp-runners/generic/setup-7.8.7.sh | sh

To use the the XP Framework development checkout, put the following in your ~/bin/xp.ini file:

use=/path/to/xp/core

Finally, start xp -v to see it working:

$ xp -v
XP 9.0.0-dev { PHP 7.1.5 & ZE 3.1.0 } @ Windows NT SLATE 10.0 build 15063 (Windows 10) AMD64

The XP Framework runs scripts or classes.

Save the following sourcecode to a file called ageindays.script.php:

<?php namespace ageindays;

use util\{Date, DateUtil};
use util\cmd\Console;

$span= DateUtil::timespanBetween(new Date($argv[1]), Date::now());
Console::writeLine('Hey, you are ', $span->getDays(), ' days old');

Now run it:

$ xp ageindays.script.php 1977-12-14
Hey, you are 13724 days old

Alternatively, you can put this code inside a class and give it a static main method. This way, you can use features like inheritance, trait inclusion etcetera. This time, save the code to a file called AgeInDays.class.php.

<?php

use util\{Date, DateUtil};
use util\cmd\Console;

class AgeInDays {

  public static function main(array $args): int {
    $span= DateUtil::timespanBetween(new Date($args[0]), Date::now());
    Console::writeLine('Hey, you are ', $span->getDays(), ' days old');
    return 0;
  }
}

Note the arguments have shifted by one: If you want the class' name, simply use self::class!

$ xp AgeInDays 1977-12-14
Hey, you are 13724 days old
