/dev/zero emulator, provides a large supply of zeroes.
Installation
Through composer:
$ composer require igorw/dev-zero:~1.0
Usage
You can call the dev_zero
function to get some zeroes.
use function igorw\dev_zero; $zeroes = dev_zero(); foreach ($zeroes as $zero) { ... }
For more advanced usage, it is possible to combine this library with nikic/iter
.
For example, you can skip the first 256 zeroes:
use function igorw\dev_zero; use function iter\drop; $zeroes = drop(2<<7, dev_zero());
Or you can convert them to a series of ones:
use function igorw\dev_zero; use function iter\map; $ones = map($n ==> $n + 1, dev_zero());
Or even chunk the zeroes into blocks of 64K:
use function igorw\dev_zero; use function iter\chunk; $blocks = chunk(dev_zero(), 64*1024);
Or if you want to get actual null bytes, you can map over the series with chr
:
use function igorw\dev_zero; use function iter\map; $nulls = map('chr', dev_zero());
Enjoy!
