+# PHP MoneyDataType - use Money as that what it is - an amount with currency
+
+A simple Money Datatype Implementation
+
+## Main Features
+
+* Contains amount AND currency as package
+* calculate with the amount
+* format with the currency
+* parse string to money datatype
+
+
+##INSTALLATION
+
+Install the package through [Composer](http://getcomposer.org/). Edit your project's `composer.json` file by adding:
+
+	"require": {
+		"bussnet/money-datatype": "*"
+	}
+
+	then run:  $ composer update
+
+or execute
+
+    composer require "bussnet/money-datatype"
+
+## Usage
+
+### Manual Currency Attributes 
+```php
+
+	$a = [
+		'code' => 'EUR',
+		'iso' => 978,
+		'name' => 'Euro',
+		'symbol_left' => '',
+		'symbol_right' => '€',
+		'decimal_place' => 2,
+		'decimal_mark' => ',',
+		'thousands_separator' => '.',
+		'unit_factor' => 100
+	];
+	$c = new \Bnet\Money\Currency('EUR', $a);
+
+```
+
+### Currency with ArrayRepository 
+```php
+
+	$repository = new ArrayRepository([
+		'EUR' => [
+			'code' => 'EUR',
+			'iso' => 978,
+			'name' => 'Euro',
+			'symbol_left' => '',
+			'symbol_right' => '€',
+			'decimal_place' => 2,
+			'decimal_mark' => ',',
+			'thousands_separator' => '.',
+			'unit_factor' => 100
+		]
+	]);
+	\Bnet\Money\Currency::registerCurrencyRepository($repository);
+
+	$c = new \Bnet\Money\Currency('EUR');
+
+```
+
+### Currency with CallbackRepository 
+```php
+
+	$repository = new \Bnet\Money\Repositories\CallbackRepository(function($code) {
+		// request the data from Database and return it 
+	});
+	\Bnet\Money\Currency::registerCurrencyRepository($repository);
+
+	$c = new \Bnet\Money\Currency('EUR');
+
+```
+
+### Money 
+```php
+
+	// assign own currency
+	$m = new Money(123456, 'EUR');
+	$m = new Money(123456, new Currency('EUR'));
+	
+	// use systemwide default currency
+	$m = new Money(123456);
+
+	// int 123456
+	$m->amount();
+	
+	// float 1234.56
+	$m->normalize();
+	
+	// 1234,56€
+	$m->format();
+
+	// 1.234,56€ (with thousand mark)
+	$m->format(true);
+	
+	// 1.234,56 EUR (with thousand mark ans code instead of sign)
+	$m->format(true, true);
+	
+	// EUR 1.234,56 (with thousand mark ans code instead of sign swap before/after part)
+	$m->format(true, true, true);
+	
+	// 1234,56€ with html spans arround the parts
+	$m->html(/* use the same params as format() above */);
+	
+	// parse Moneystrings -> 123456 cents
+	$m = Money::parse('1.234,56');
+	// +/- sign before is allowed, currency sign is not allowed
+	// the first ./, is interpreted as thousand mark, the second as decimal makr - more than two are not allowed
+
+```
