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:
1$subdomain = Pipe::from('https://blog.sebastiaanluca.com')2 ->parse_url()3 ->end()4 ->explode('.', PIPED_VALUE)5 ->reset()6 ->get();78// "blog"
Under the hood, the
Pipe class will call the native PHP methods such as
end(), etc., however, using method chaining helps the readability of code and is potentially less error-prone than a one-liner or procedural code like the following:
1$subdomain = 'https://blog.sebastiaanluca.com/';2$subdomain = parse_url($subdomain, PHP_URL_HOST);3$subdomain = explode('.', $subdomain);4$subdomain = reset($subdomain);
When you need more flexibility, this package also supports custom closures and the use of class methods:
1// Closure2Pipe::from('string')3 ->pipe(fn(string $value): string => 'prefixed-' . $value)4 ->get();56// Class-based methods7Pipe::from('HELLO')8 ->pipe([$this, 'lowercase'])9 ->get();
