Introduction

This package is based on the pipe operator RFC by Sara Golemon and Marcelo Camargo (2016), who explains the problem as:

A common PHP OOP pattern is the use of method chaining, or what is also known as “Fluent Expressions”. […] This works well enough for OOP classes which were designed for fluent calling, however it is impossible, or at least unnecessarily arduous, to adapt non-fluent classes to this usage style, harder still for functional interfaces.

Short example

Say you want to get the subdomain from a URL, you may get quite verbose and repetitive code like this:

$result = 'https://blog.github.com';
$result = parse_url($result);
$result = end($result);
$result = explode('.', $result);
$result = reset($result);

// blog

More examples

See the RFC by Golemon and Marcelo Camargo for more complex and real-world examples.

Installation

You can install the package via Composer:

composer require boostphp/pipe-operator

Usage

You could use the package like this:

use Boost\PipeOperator\PipeOperator;

$result = PipeOperator::from('https://blog.github.com')
    ->parse_url()
    ->end()
    ->explode('.', PIPED_VALUE)
    ->reset()
    ->get();

// blog

Using closures

You could also use closures for more flexibility:

use Boost\PipeOperator\PipeOperator;

$result = PipeOperator::from('https://blog.github.com')
    ->pipe(fn ($value) => md5($value))
    ->pipe(fn ($value) => sprintf('prefixed-%s', $value))
    ->get();
