Important

Starting with PHP 8.6, this package will become obsolete as the `clamp()` function will be natively available in PHP. See the [PHP RFC: clamp() function v2](https://wiki.php.net/rfc/clamp_v2) for more details.

Installation
------------

[](#installation)

The recommended way of installing Larvatar is to use [Composer](https://getcomposer.org/). Run the following command to install it to you project:

```
composer require renfordt/clamp

```

Usage
-----

[](#usage)

The usage is very simple and comparable to the C++ function:

```
clamp(
    $value, // The value to be clamped
    $min, // The minimum value to clamp to
    $max // The maximum value to clamp to
);
```

Alternatively you can use `clampMinMax()` which is a bit slower.

```
clampMinMax(
    $value, // The value to be clamped
    $min, // The minimum value to clamp to
    $max // The maximum value to clamp to
);
```

Why another package?
--------------------

[](#why-another-package)

Even though there are some similar packages, this one focuses on different approaches.

First of all the syntax is similar to c++ clamp function.

Secondly and more important this package focuses on performance. Other packages uses the `max($min, min($max, $num))`approach but this packages works with the following code:

```
if ($value > $max) {
    return $max;
} elseif ($value < $min) {
    return $min;
}
return $value;
```

Even though the readability is a bit worse, the performance is up to 2x faster. In most cases this is not noticeable but in some cases there will be a benefit.

Over a iteration of 100.000 executions the functions need the following times:
