|
Psl is a standard library for PHP, inspired by [hhvm/hsl](https://github.com/hhvm/hsl).
|
|
|
|
The goal of Psl is to provide a consistent, centralized, well-typed set of APIs for PHP programmers.
|
|
|
|
## Example
|
|
|
|
```php
|
|
<?php
|
|
|
|
declare(strict_types=1);
|
|
|
|
use Psl\{Str, Vec};
|
|
|
|
/**
|
|
* @psalm-param iterable<?int> $codes
|
|
*/
|
|
function foo(iterable $codes): string
|
|
{
|
|
$codes = Vec\filter_nulls($codes);
|
|
|
|
$chars = Vec\map($codes, fn(int $code): string => Str\chr($code));
|
|
|
|
return Str\join($chars, ', ');
|
|
}
|
|
|
|
foo([95, 96, null, 98]);
|
|
// 'a, b, d'
|
|
```
|
|
|
|
