inetprocess/transformation

Inspired by Respect/Validation, that library transforms an input string (or float / int / bool) to an output string, after applying rules.

The benefit using it is that it a generic wrapper for any kind of transformation. Also it throws Exceptions and allows to chain the transformations.

Usage

It's pretty simple to use. suppose you need to transform a date "31-12-2012" to another format such as "2012-12-31". Just do:

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Inet\Transformation\Transform as T;

$dateEntered = '31-12-2012';
$output = T::Date('d-m-Y', 'Y-m-d')->transform($dateEntered);
echo $output;

Now if you need to change the format then the Timezone:

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Inet\Transformation\Transform as T;

$dateEntered = '31-12-2012 23:21:58';
$output = T::Date('d-m-Y H:i:s', 'Y-m-d H:i:s')->Timezone('Y-m-d H:i:s', 'Asia/Calcutta')->transform($dateEntered);
// Displays: 2013-01-01 03:51:58
echo $output;

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.

T::Callback('sprintf', "REF%'06d")->transform(1234); // REF001234

CopyFileToUuid(string $sourceDir, string $destinationDir)

Copy a file with a filename to a UUID generated name. Return the generated UUID.

T::CopyFileToUuid('/var/www/upload/', '/var/www/unified_upload')->transform('quotes/client_01.pdf'); // 123e4567-e89b-12d3-a456-426655440000

## 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.

T::Explode(',')->transform('foo,bar,baz'); // array('foo', 'bar', 'baz');
T::Explode(',')->Implode('|')->transform('foo,bar,baz'); // foo|bar|baz

Htmlspecialchars([array $flags, string $encoding, bool $double_encoding])

Encode special chars. Uses htmlspecialchars function from PHP.

T::Htmlspecialchars(['ENT_QUOTES'])->transform("l'arbre"); // l'arbre
T::Htmlspecialchars(['ENT_QUOTES'], 'UTF-8', false)->transform("l'arbre"); // l'arbre

HtmlspecialcharsDecode([array $flags])

Decode special chars. Uses htmlspecialchars_decode function from PHP.

T::HtmlspecialcharsDecode(['ENT_QUOTES'])->transform("l'arbre"); // l'arbre

Implode(string $delimiter)

Join an array elements to a string. Uses implode function from 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

$mapping = array(
    '1' => 'key1',
    '10' => 'key10',
);
T::Map($mapping)->transform('1'); // key1
T::Map($mapping)->transform(array('10', '1')); // array('key10', 'key1')
T::Map($mapping)->transform('unknown key'); // unknown key

MimeType([string $root])

Return the MimeType of the file. The first optional parameter allow to specify a root directory prepend to the filename

T::MimeType()->transform('test.jpg'); // image/jpeg
T::MimeType('uploads')->transform('logo.png'); // image/png

NormalizeURL(string $protocol)

Prepend a default protocol if not present to any url.

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).

T::Replace('a', 'b')->transform('ababa'); // bbbbb

ReplaceRegexp(string $pattern, string $replacement)

Replace a pattern by a replacement (does the same than preg_replace).

T::ReplaceRegexp('/^fox/', 'rabbit')->transform('fox and foxes'); // rabbit and foxes

Slugify()

Uses Cocur\Slugify to Slugify a string.

T::Slugify()->transform('Bonjour tôôut le monde !'); // bonjour-toout-le-monde

SetType()

Uses settype from PHP for type casting.

T::SetType('bool')->transform('1'); // true
T::SetType('bool')->transform('0'); // false
T::SetType('bool')->transform(array()); // false

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

$mapping = array(
    '1' => 'key1',
    '10' => 'key10',
);
T::SugarCRMMapMultiEnum($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])

Change the Timezone of a Date by providing the format, the target Timezone and optionnaly the timezone for the current date.

See example above
