JBZoo / SimpleTypes

The universal PHP library to convert any values and measures - money, weight, currency coverter, length and what ever you want ;)

Installation

composer require jbzoo/simpletypes

Examples

use JBZoo\SimpleTypes\Config;
use JBZoo\SimpleTypes\Money;
use JBZoo\SimpleTypes\ConfigMoney;

// Set config object for all Money objects as default
Config::registerDefault('money', new ConfigMoney());

// Create any object, some different ways
$money  = new Money('10 eur');
$weight = new Weight('1000'); // Gram is default in the ConfigWeight class
$length = new Length('500 km');
$money  = new Money('100500 usd', new ConfigMoney()); // my custom params only for that object

A lot of types are ready to use

SimpleTypes has such ready configurations like

• Area
• Degree (geometry)
• Info (bytes, bits...)
• Length
• Money (Currency converter)
• Temperature (Kelvin, Fahrenheit, Celsius and etc)
• Volume
• Weight

You can add your own type. It's really easy. See this page below.

Smart and useful parser

SimpleTypes has really smart parser for all input values. It can find number, understand any decimal symbols, trim, letter cases, e.t.c... and it works really fast!

$money = new Money(' - 1 2 3 , 4 5 6 rub ');    // Equals -123.456 rubles
$money = new Money('1.0e+18 EUR ');             // Really huge number. I'm rich! =)
$money = new Money('  EuR 3,50   ');
$money = new Money('usd');                      // Just object with usd rule

Chaining method calls

$value = (new Money('4.95 usd'))
    ->add('10 usd')                         // $14.95
    ->subtract('2 eur')                     // $10.95
    ->negative()                            // -$10.95
    ->getClone()                            // copy of object is created
    ->division(5)                           // -$2.19
    ->multiply(10)                          // -$21.90
    ->convert('eur')                        // -10.95€ (For easy understanding we use 1 EUR = 2 USD)
    ->customFunc(function (Money $value) {  // sometimes we would like something more than plus/minus ;)
        $value
            ->add(new Money('600 rub'))     // 1.05€ (1 EUR = 50 RUB)
            ->add('-500%');                 // -4.2€
    })
    ->abs();                                // 4.2€

Basic arithmetic

Different ways to use basic arithmetic

// example #1
$usd = new Money('10 usd');
$usd->add(new Money('10 eur'));

// example #2
$usd = (new Money('10 usd'))->add(new Money('10 eur'));

// example #3
$usd->add('10 eur');

// example #4
$usd->add('10'); // eur is default in the ConfigMoney

// example #5
$usd->add(['10', 'eur']);

SimpleTypes can

• add
• subtract
• division
• multiply
• use custom functions (Closure)
• negative / positibe / invert sign / abs
• use percent
• setting empty value
• setting another value and rule
• create clone
• converting to any rules (currencies, units)
• rounding
• comparing
• ... and others

Compare values

$kg = new Weight('1 kg'); // one kilogram
$lb = new Weight('2 lb'); // two pounds

var_dump($kg->compare($lb));            // false ("==" by default)
var_dump($kg->compare($lb, '=='));      // false
var_dump($kg->compare($lb, '<'));       // false
var_dump($kg->compare($lb, '<='));      // false
var_dump($kg->compare($lb, '>'));       // true
var_dump($kg->compare($lb, '>='));      // true

And same examples but we will use smart parser

$kg = new Weight('1 kg');
$lb = new Weight('2 lb');

var_dump($kg->compare('1000 g'));       // true
var_dump($kg->compare('2 lb', '=='));   // false
var_dump($kg->compare('2 lb', '<'));    // false
var_dump($kg->compare('2 lb', '<='));   // false
var_dump($kg->compare('2 lb', '>'));    // true
var_dump($kg->compare('2 lb', '>='));   // true

Percent method

Simple way for count difference between two values

$origPrice = new Money('100 usd');
$realPrice = new Money('40 eur');

$diff = $realPrice->percent($origPrice);
echo $diff->text(); // 80%

$discount = $realPrice->percent($origPrice, true); // revert flag added
echo $discount->text(); // 20%

PHP magic methods

Safe serialize/unserialize

$valBefore = $this->val('500 usd');
$valString = serialize($valBefore);
$valAfter  = unserialize($valString)->convert('eur');
$valBefore->compare($valAfter);// true

__toString() works like text() method

$val = $this->val('500 usd');
echo $val; // "$500.00"

__invoke()

$val = $this->val('10 eur');
// it's converting
$val('usd'); // so object now contains "20 usd" (1 eur = 2 usd)
// set new value and rule
$val('100 rub');
$val('100', 'uah');

Different ways for output and rendering

Only text

$value = new Money('-50.666666 usd');
echo $value->text();            // "-$50.67"
echo $value->text('rub');       // "-1 266,67 руб." (output without changing inner state)
echo $value->noStyle('rub');    // "-1 266,67" (without symbol)

Simple HTML rendering

echo (new Money('-50.666666 usd'))->html('rub'); // render HTML, useful for JavaScript

Output (warping added just for clarity)

<span
    class="simpleType simpleType-block simpleType-money"
    data-simpleType-id="1"
    data-simpleType-value="-1266.66665"
    data-simpleType-rule="rub"
    data-simpleType-orig-value="-50.666666"
    data-simpleType-orig-rule="usd">
        -<span class="simpleType-value">1 266,67</span>
        <span class="simpleType-symbol">руб.</span>
</span>

HTML Input type[text]

echo $value->htmlInput('rub', 'input-name-attr');

Output (warping added just for clarity)

<input
    value="-1 266,67"
    name="input-name-attr"
    type="text"
    class="simpleType simpleType-money simpleType-input"
    data-simpleType-id="1"
    data-simpleType-value="-1266.66665"
    data-simpleType-rule="rub"
    data-simpleType-orig-value="-50.666666"
    data-simpleType-orig-rule="usd"
/>

Notice: Yes, we added a lot of data-attributes in the HTML code. It will be useful for JavaScript and converting without reload a page.

Configuration of type

All configuration classes should be extended from Config class For example, config for information

/**
 * Class ConfigInfo
 * @package JBZoo\SimpleTypes
 */
class ConfigInfo extends Config
{
    /**
     * SimpleTypes uses it for converting and while parsing undefined values
     * @var string
     */
    public $default = 'byte';
    
    /**
     * To collect or not to collect logs for each object (need additional memory a little bit)
     * @var bool
     */
    public $isDebug = true;
    
    /**
     * Array of converting rules and output format
     * return array
     */
    public function getRules()
    {
        // key of array is alias for parser
        return array(
            'byte' => array(
                'rate' => 1 // Because 1 byte to byte is 1 =)))
            ),

            'kb'   => array(
                'symbol'          => 'KB',                     // symbol for output (->text(), ->html(), ...)
                'round_type'      => Formatter::ROUND_CLASSIC, // classic, float, ceil, none
                'round_value'     => Formatter::ROUND_DEFAULT, // Count of valuable number after decimal point for any arithmetic actions
                'num_decimals'    => '2',       // Sets the number of decimal points
                'decimal_sep'     => '.',       // Sets the separator for the decimal point.
                'thousands_sep'   => ' ',       // Sets the thousands separator.
                'format_positive' => '%v %s',   // %v - replace to rounded and formated (number_format()) value
                'format_negative' => '-%v %s',  // %s - replace to symbol
                'rate'            => 1024,      // How many bytes (default measure) in the 1 KB ?
            ),

            'mb'   => array( // Other params gets from $this->defaultParams variable
                'symbol' => 'MB',
                'rate'   => 1024 * 1024,
            ),

            'gb'   => array( // Other params gets from $this->defaultParams variable
                'symbol' => 'GB',
                'rate'   => 1024 * 1024 * 1024,
            ),

            'bit'  => array(
                'symbol' => 'Bit',
                'rate'   => function ($value, $to) { // Custom callback function for difficult conversion
                    if ($to == 'bit') {
                         return $value * 8;
                    }
                    return $value / 8;
                },
            ),
        );
    }
}

Usage example for our information type

// create config object
$config = new ConfigInfo();

// you can register default config for all info-objects,
Config::registerDefault('info', $config);
$info1 = new Info('700 MB');
$info2 = new Info('1.4 GB');

// or add config object manually
$info1 = new Info('700 MB', $config);
$info2 = new Info('1.4 GB', $config);

// Well... some calculations
echo $info2->subtract($info1)->dump() . PHP_EOL;
echo $info2->convert('mb')->dump() . PHP_EOL;
print_r($info2->logs());

Output

0.71640625 gb; id=4
733.6 mb; id=4
Array
(
    [0] => Id=4 has just created; dump="1.4 gb"
    [1] => Subtract "700 mb"; New value = "0.71640625 gb"
    [2] => Converted "gb"=>"mb"; New value = "733.6 mb"; 1 gb = 1024 mb
)

Debug information

Show list of all actions with object. For example, this is history for chaining code

print_r($value->logs());

/**
 * Array
 * (
 *     [0]  => Id=16 has just created; dump="4.95 usd"
 *     [1]  => Add "10 usd"; New value = "14.95 usd"
 *     [2]  => Subtract "2 eur"; New value = "10.95 usd"
 *     [3]  => Set negative; New value = "-10.95 usd"
 *     [4]  => Cloned from id=16 and created new with id=19; dump=-10.95 usd
 *     [5]  => Division with "5"; New value = "-2.19 usd"
 *     [6]  => Multiply with "10"; New value = "-21.9 usd"
 *     [7]  => Converted "usd"=>"eur"; New value = "-10.95 eur"; 1 usd = 0.5 eur
 *     [8]  => --> Function start
 *     [9]  => Add "600 rub"; New value = "1.05 eur"
 *     [10] => Add "-500 %"; New value = "-4.2 eur"
 *     [11] => <-- Function finished; New value = "-4.2 eur"
 *     [12] => Set positive/abs; New value = "4.2 eur"
 * )
 */

Show real inner data without any formating and rounding. ID is unique number for SimpleType objects.

echo $value->dump(); // "4.2 eur; id=19"

Get object id

echo $value->getId(); // "19"

Show current value

echo $value->val(); // "4.2"

Show current rule

echo $value->rule(); // "eur"
