```

composer require srph/map-range

```

A more efficient `foreach`-`range`.

## Usage

```php

SRPH\MapRange\map_range(function($index) {

	// do something

}, $from, $to);

```

For PHP >=v5.6, you can use the use function (aka import function) syntax:

```php

use function SRPH\MapRange\map_range;

map_range(function($index) {

	// do something

}, $from, $to);

```

Note that it iterates *while* `$from <= $to`.

## Why

Because some developers prefer this

```php

foreach(range(0, 10) as $i) {

	// ..

} 

```

Over this:

```php

for ( $i = 0; $i < 10; $i++ ) {

	//

}

```

In which the first example generates a buffer array first (which is terrible for performance).
