🔡 Portable ASCII

Description

It is written in PHP (PHP 7+) and can work without "mbstring", "iconv" or any other extra encoding php-extension on your server.

The benefit of Portable ASCII is that it is easy to use, easy to bundle.

The project based on ...

Alternative

If you like a more Object Oriented Way to edit strings, then you can take a look at voku/Stringy, it's a fork of "danielstjules/Stringy" but it used the "Portable ASCII"-Class and some extra methods.

// Portable ASCII
use voku\helper\ASCII;
ASCII::to_transliterate('déjà σσς iıii'); // 'deja sss iiii'

// voku/Stringy
use Stringy\Stringy as S;
$stringy = S::create('déjà σσς iıii');
$stringy->toTransliterate();              // 'deja sss iiii'

Install "Portable ASCII" via "composer require"

composer require voku/portable-ascii

Why Portable ASCII?

I need ASCII char handling in different classes and before I added this functions into "Portable UTF-8", but this repo is more modular and portable, because it has no dependencies.

Requirements and Recommendations

  • No extensions are required to run this library. Portable ASCII only needs PCRE library that is available by default since PHP 4.2.0 and cannot be disabled since PHP 5.3.0. "\u" modifier support in PCRE for ASCII handling is not a must.
  • PHP 7.0 is the minimum requirement

Usage

Example: ASCII::to_ascii()

  echo ASCII::to_ascii('�Düsseldorf�', 'de');
  
  // will output
  // Duesseldorf

  echo ASCII::to_ascii('�Düsseldorf�', 'en');
  
  // will output
  // Dusseldorf

Portable ASCII | API

The API from the "ASCII"-Class is written as small static methods.

Class methods

charsArray(bool $withExtras = false): array

Returns an replacement array for ASCII methods.

$array = ASCII::charsArray();

var_dump($array['ru']['б']); // 'b'
charsArrayWithMultiLanguageValues(bool $withExtras = false): array

Returns an replacement array for ASCII methods with a mix of multiple languages.

$array = ASCII::charsArrayWithMultiLanguageValues();

var_dump($array['b']); // ['β', 'б', 'ဗ', 'ბ', 'ب']
charsArrayWithOneLanguage(string $language = 'en', bool $withExtras = false): array {

Returns an replacement array for ASCII methods with one language.

For example, German will map 'ä' to 'ae', while other languages will simply return e.g. 'a'.

$array = ASCII::charsArrayWithOneLanguage('ru');

$tmpKey = \array_search('yo', $array['replace']);
echo $array['orig'][$tmpKey]; // 'ё'
charsArrayWithSingleLanguageValues(bool $withExtras = false): array

Returns an replacement array for ASCII methods with multiple languages.

$array = ASCII::charsArrayWithSingleLanguageValues();

$tmpKey = \array_search('hnaik', $array['replace']);
echo $array['orig'][$tmpKey]; // '၌'
is_ascii(string $str) : bool

Checks if a string is 7 bit ASCII.

ASCII::is_ascii(''); // false
normalize_msword(string $str) : string

Normalize some MS Word special characters.

ASCII::normalize_msword('„Abcdef…”'); // '"Abcdef..."'
normalize_whitespace(string $str, bool $keepNonBreakingSpace = false, bool $keepBidiUnicodeControls = false) : string

Normalize the whitespace.

ASCII::normalize_whitespace("abc-\xc2\xa0-öäü-\xe2\x80\xaf-\xE2\x80\xAC", true); // "abc-\xc2\xa0-öäü- -"
to_ascii(string $str, string $language = 'en', bool $removeUnsupported = true): string

Convert a string into language specific ASCII.

ASCII::to_ascii('�Düsseldorf�', 'en'); // Dusseldorf
to_filename(string $str, bool $use_transliterate = false, string $fallback_char = '-'): string

Convert given string to safe filename (and keep string case).

ASCII::to_filename('שדגשדג.png', true)); // 'shdgshdg.png'
to_transliterate(string $str, string $unknown = '?', bool $strict) : string

Convert a string into ASCII.

ASCII::to_transliterate('déjà σσς iıii'); // 'deja sss iiii'

Unit Test

  1. Composer is a prerequisite for running the tests.
composer install
  1. The tests can be executed by running this command from the root directory:
./vendor/bin/phpunit
