A PHP Package to Calculate Dive Stats from the PADI RDP
-------------------------------------------------------

[](#a-php--package-to-calculate-dive-stats-from-the-padi-rdp)

**This package is for informational use only, the author accepts no liability for calculations made using this package!**

**All divers should perform and check their own calculations with approved charts or devices.**

### Installation

[](#installation)

The easiest way to install is through composer

```
composer require ambielecki/divecalculator

```

Or in your require section add:

```
"require": {
    "ambielecki/dive-calculator": "1.*"
}

```

Run

```
composer update

```

And you should be good to go.

### Simple Usage

[](#simple-usage)

Pardon the formating, markdown and all.

All times should be in minutes, all depths in feet. I'm in the US, so only Imperial for now.

```
use Ambielecki\DiveCalculator\DiveCalculator;

$depth = 50;
$time = 45;
$diveCalculator = new DiveCalculator();
$pressuregroup = $diveCalculator->getPressureGroup($depth, $time);
```

### Available Methods

[](#available-methods)

getPressureGroup($depth, $time, $residual\_time = null)

getNewPressureGroup($starting\_group, $surface\_interval)

getResidualNitrogenTime($pressure\_group, $depth)

getMaxBottomTime($depth, $rnt = 0)
