dev-zero
/dev/zero emulator, provides a large supply of zeroes.
Installation
Through composer:
$ composer require igorw/dev-zero:~1.0Usage
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!
