# moon - A command-line php for the Moon Phase

CLI script `moon.php` instantiates class [solarissmoke/php-moon-phase](https://github.com/solarissmoke/php-moon-phase) and echoes JSON if successful

The script can also be run as a web-service with PHP's in-built webserver for testing the JSON request/responses.

*NOTE:* Originally this script called the burning soul REST API to get the data, that
previous code is on this branch: https://github.com/vijinho/moon/tree/burningsoul

## Features

- Runs on the command-line
- Can be called as a stand-alone webservice using the php command line built-in server
- All messages when running with `--debug` or `--verbose` are to *stderr* to avoid interference with *stdout*
- Can output the result if successful to *stdout*
- Specify date-format using [php date()](https://secure.php.net/manual/en/function.date.php)
- Errors are output in JSON as 'errors' with just a bunch of strings

```
{
"errors": [
"Unable to parse --date: next sunsaday"
]
}
```

## Returned results fields/columns/keys

- `phase`: the terminator phase angle as a fraction of a full circle (i.e., 0 to 1). Both 0 and 1 correspond to a New Moon, and 0.5 corresponds to a Full Moon.
- `illumination`: the illuminated fraction of the Moon (0 = New, 1 = Full).
- `age_days`: the age of the Moon, in days.
- `distance_km`: the distance of the Moon from the centre of the Earth (kilometres).
- `diameter`: the angular diameter subtended by the Moon as seen by an observer at the centre of the Earth (degrees).
- `sun_distance_km`: the distance to the Sun (kilometres).
- `sun_diameter`: the angular diameter subtended by the Sun as seen by an observer at the centre of the Earth (degrees).
- `new_moon`: the time of the last New Moon (UNIX timestamp).
- `next_new_moon`: the time of the next New Moon (UNIX timestamp).
- `full_moon`: the time of the Full Moon in the current lunar cycle (UNIX timestamp).
- `next_full_moon`: the time of the next Full Moon in the current lunar cycle (UNIX timestamp).
- `first_quarter`: the time of the first quarter in the current lunar cycle (UNIX timestamp).
- `next_first_quarter`: the time of the next first quarter in the current lunar cycle (UNIX timestamp).
- `last_quarter`: the time of the last quarter in the current lunar cycle (UNIX timestamp).
- `next_last_quarter`: the time of the next last quarter in the current lunar cycle (UNIX timestamp).
- `phase_name`: the [phase name](http://aa.usno.navy.mil/faq/docs/moon_phases.php).
- `stage`: the phase waxing/waning

## Instructions

### Save to file example

`php moon.php --date='next year' > test.json`

## Running as a webservice

### Starting the service

1. Start the PHP webserver with `php -S 127.0.0.1:12312`
2. Browse the URL: http://127.0.0.1:12312/moon.php with GET/POST parameters as 'date=' and 'round' for rounding or no param for NOW.

### Webservice Example

Search for moon phase 'next sunday' with rounding:

http://127.0.0.1:12312/moon.php?date=next%20sunday&round

Result:

```
