A well-structured and easy-to-use PHP class providing access to Unicode utilities. This class allows working with Unicode characters in a type-safe and explicit manner for PHP applications by providing constants and methods to retrieve subsets of characters, escape Unicode sequences, and more.

• Unicode constants for type-safe and explicit declarations
• Retrieve all Unicode constants defined in the class
• Fetch a subset of Unicode constants by count or range
• Convert UTF-8 characters to Unicode escape sequences
• Provides structured access to Unicode symbols
• Ensures strict type safety for better maintainability

use Rayblair\Unicode\Unicode;

echo Unicode::HYPHEN_MINUS; // Outputs: -

$mappings = [
    Unicode::EN_DASH => Unicode::HYPHEN_MINUS,
    Unicode::EM_DASH => Unicode::HYPHEN_MINUS,
];

1. Install via Composer:

composer require rayblair/unicode

use Rayblair\Unicode\Unicode;

// Get single Unicode constant
print_r(Unicode::HYPHEN_MINUS); // Outputs: -

// Get all Unicode constants
print_r(Unicode::getAll());

// Get first 10 Unicode constants
print_r(Unicode::get(10));

// Get Unicode characters within a specific range
print_r(Unicode::range('0041', '0044'));

// Convert UTF-8 characters into Unicode escape sequences
echo Unicode::escape('A'); // Outputs \u0041

Returns an associative array of all defined Unicode constants.

print_r(Unicode::getAll());

Output Example:

Array
(
    [LATIN_CAPITAL_LETTER_A] => A
    [LATIN_CAPITAL_LETTER_B] => B
    [LATIN_SMALL_LETTER_A] => a
)

Returns a subset of Unicode constants up to the given count.

print_r(Unicode::get(5));

Returns a subset of Unicode constants within a specified Unicode hex range.

print_r(Unicode::range('0041', '0044'));

Output:

Array
(
    [LATIN_CAPITAL_LETTER_A] => A
    [LATIN_CAPITAL_LETTER_B] => B
    [LATIN_CAPITAL_LETTER_C] => C
    [LATIN_CAPITAL_LETTER_D] => D
)

Converts UTF-8 characters into Unicode escape sequences (\uXXXX).

echo Unicode::escape('Hello, 😊!'); // Outputs: \u0048\u0065\u006c\u006c\u006f, \u1F60A!

• PHP 8.0 and above
