PHP Pipe Operator is a package by Sebastiaan Luca that provides a userland implementation of the pipe operator in PHP. A recent RFC proposed this feature for PHP 8.1 but is declined with a majority "no" vote.
This package aims to bridge the lack of native pipe operator by taking a value and performing one or more actions on it:
$subdomain = Pipe::from('https://blog.sebastiaanluca.com')
->parse_url()
->end()
->explode('.', PIPED_VALUE)
->reset()
->get();
// "blog"
Under the hood, the Pipe
class will call the native PHP methods such as parse_url()
, end()
, etc., however, using method chaining helps the readability of code and is potentially less error-prone than a one-liner or procedural code like the following:
$subdomain = 'https://blog.sebastiaanluca.com/';
$subdomain = parse_url($subdomain, PHP_URL_HOST);
$subdomain = explode('.', $subdomain);
$subdomain = reset($subdomain);
When you need more flexibility, this package also supports custom closures and the use of class methods:
// Closure
Pipe::from('string')
->pipe(fn(string $value): string => 'prefixed-' . $value)
->get();
// Class-based methods
Pipe::from('HELLO')
->pipe([$this, 'lowercase'])
->get();
