 # Transformation Rules
 For now there is only a few rules. I'll add more later, and don't hesitate if you want to contribute.
 
+## Callback(string $functionName, [$param1, $param2, ...])
+Call any php function on input. The input will be passed as the last argument of the function.
+```php
+T::Callback('sprintf', "REF%'06d")->transform(1234); // REF001234
+```
+
+## Concat(string $before, [string $after])
+Append and prepend string to input.
+```php
+T::Concat('REF')->transform('1234'); // REF1234
+T::Concat('REF', 'AB')->transform('1234'); // REF1234AB
+```
+
 ## Date(string $inputFormat, string $outputFormat)
 Transforms a date from a format to another.
 
 _See example above_
 
+## Explode(string $delimiter)
+Explode a string to an array using a delimiter. Uses `explode` function from PHP.
+It returns an array.
+```php
+T::Explode(',')->transform('foo,bar,baz'); // array('foo', 'bar', 'baz');
+T::Explode(',')->Implode('|')->transform('foo,bar,baz'); // foo|bar|baz
+```
+
+## Implode(string $delimiter)
+Join an array elements to a string. Uses `implode` function from PHP.
+```php
+T::Implode('@')->transform(array('foo', 'bar')); // foo@bar
+```
+
+## Map(array $mapping)
+Try to replace the input with the value in the mapping.
+It can also work with an array as input.
+Values not found in mapping are return without tranformations
+
+```php
+$mapping = array(
+    '1' => 'key1',
+    '10' => 'key10',
+);
+T::Map($mapping)->transform('1'); // key1
+T::Map($mapping)->transform(array('10', '1')); // array('key10', 'key1')
+T::Map($mapping)->transform('unknown key'); // unknown key
+```
+
+## NormalizeUrl(string $protocol)
+Prepend a default protocol if not present to any url.
+```php
+T::NormalizeUrl('http')->transform('https://www.google.com'); // https://www.google.com
+T::NormalizeUrl('http')->transform('www.google.com'); // http://www.google.com
+T::NormalizeUrl('http')->transform('ssh://github.com'); // ssh://github.com
+T::NormalizeUrl('ssh')->transform('github.com'); // ssh://github.com
+```
+
 ## Replace(string $search, string $replace)
 Replace a string by another (does the same than str_replace).
 ```php
-<?php
-require_once __DIR__ . '/vendor/autoload.php';
-use Inet\Transformation\Transform as T;
-
-$str = 'abababababab';
-$output = T::Replace('a', 'b')->transform($str);
-echo $output;
+T::Replace('a', 'b')->transform('ababa'); // bbbbb
 ```
 
 
 ## ReplaceRegexp(string $pattern, string $replacement)
 Replace a pattern by a replacement (does the same than preg_replace).
 ```php
-<?php
-require_once __DIR__ . '/vendor/autoload.php';
-use Inet\Transformation\Transform as T;
-
-$str = 'abababababab';
-$output = T::ReplaceRegexp('/a/', 'b')->transform('abababababab');
-echo $output;
+T::ReplaceRegexp('/^fox/', 'rabbit')->transform('fox and foxes'); // rabbit and foxes
 ```
 
 ## Slugify()
 Uses [Cocur\Slugify](https://github.com/cocur/slugify) to Slugify a string.
 ```php
-<?php
-require_once __DIR__ . '/vendor/autoload.php';
-use Inet\Transformation\Transform as T;
+T::Slugify()->transform('Bonjour tôôut le monde !'); // bonjour-toout-le-monde
+```
 
-$output = T::Slugify()->transform('Bonjour tôôut le monde !');
-// Displays: bonjour-toout-le-monde
-echo $output;
+## SugarCRMMapMultiEnum(array $mapping, [array $options])
+Map multiple values from a string or an array
+and return a string encoded for database storage of SugarCRM multi enum field.
+String are exploded first with the default separator `|`.
+You can set the following options
+* `separator`: Separator to use to explode input string. Default: `|`
+* `from_multi_enum`: If true parse the input string as a SugarCRM multi enum field. Default: `false`
+```php
+$mapping = array(
+    '1' => 'key1',
+    '10' => 'key10',
+);
+T::SugarCRMMapMultiEnum($mapping)->transform('1|10'); // ^key1^,^key10^
+T::SugarCRMMapMultiEnum($mapping)->transform(array('1', '10'); // ^key1^,^key10^
+T::SugarCRMMapMultiEnum($mapping)->transform('^1^,^23^', array('from_multi_enum' => true)); // ^key1^,^23^
 ```
 
 ## Timezone(string $inputFormat, string $targetTimezone, [string $currentTimezone])
