introduction

With Phunc library I share ideas practice software examples. "how to use simple functional PHP with usage objecting representation" utilities for functional programming.

Phunctional thinking

If you are not happy with functions in PHP to implements functional programming, try to use objects. PHP objects can help with:

• define
• transport
• conversion
• controlling

Example functional programming with strong typing

Example PHP CLASS

class Dump
{    
    public function __construct(ArrayObject $array)
    {
        // first variable
        try {
                if(empty($array->first)){
                    throw new Exception('Undefined property: first'); 
                }
                var_dump($array->first);
                
                
        } catch( Exception $e ) {
           echo 'Problem with ' . $e->getMessage() . "\n";
        }
         
        // second variable
        try {
            if(empty($array->second))
            {
                throw new Exception('Undefined property: second'); 
            }
            var_dump($array->second);
            
        } catch( Exception $e ) {
           echo 'Problem with ' . $e->getMessage() . "\n";
        }
    }
}

1. Example without parameters

Code

$a = new ArrayObject();
new Dump( $a );

Result

Problem with Undefined property: first
Problem with Undefined property: second

2. Example with first parameter

Code

$a = new ArrayObject();
$a->first = 1;
new Dump( $a );

Result

int(1)
Problem with Undefined property: second

3. Example with both parameters

Code

$a = new ArrayObject();
$a->first = 1;
$a->second = 2;
new Dump( $a );

Result

int(1)
int(2)

packagist phunc

Install in PHPstorm based on composer project

Easy way to install Phunc with APICRA

Linux

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

Windows

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
