README

A lightweight polyfill that provides a pipe() function for method chaining in PHP 5.6+ applications. This function allows you to chain method calls on objects or apply closures in a clean, readable way.

Installation

Via Composer

composer require datahihi1/polyfill-pipefn

Manual Installation

Download the pipeFunction.php file
Include it in your project:
```
require_once 'pipeFunction.php';
```

Usage

The pipe() function takes an initial value and chains it through multiple methods or closures.

Basic Syntax

$result = pipe($value, ...$methods);

Parameters

$value - The initial value to be piped through the methods
...$methods - Variable number of methods, which can be:
- String method names (for object methods)
- Arrays in format ['methodName', [arguments]]
- Closures/functions

Examples

You can see a real-world example in the files in the demo folder to better understand how to use the pipe function.

Method Types

1. String Method Names

pipe($object, 'methodName');

2. Methods with Arguments

pipe($object, ['methodName', [arg1, arg2, ...]]);

3. Closures/Functions

pipe($value, function($value) {
    // Process $value
    return $processedValue;
});

PHP >= 5.6
No additional dependencies
