Features

• Type description: Human-readable type strings for error messages (primitives, arrays, NaN, Infinity)
• HTML escaping: Escape &, <, >, ", ' for safe output and XSS mitigation
• Random sequences: Generate numeric, alphabetic, or alphanumeric sequences of any length
• URI encoding: Percent-encode/decode URI components (path, query, fragment) per RFC 3986
• Zero dependencies: No production dependencies

Installation

composer require lacus/utils

Quick Start

<?php

use Lacus\Utils\HtmlUtils;
use Lacus\Utils\SequenceGenerator;
use Lacus\Utils\SequenceType;
use Lacus\Utils\TypeDescriber;
use Lacus\Utils\UrlUtils;

TypeDescriber::describe(null);                    // 'null'
TypeDescriber::describe('hello');                 // 'string'
TypeDescriber::describe(42);                      // 'integer number'
TypeDescriber::describe([1, 2, 3]);               // 'number[]'

HtmlUtils::escape('Tom & Jerry');                 // 'Tom &amp; Jerry'
HtmlUtils::unescape('Tom &amp; Jerry');           // 'Tom & Jerry'

SequenceGenerator::generate(10, SequenceType::Numeric);       // e.g. '9956000611'
SequenceGenerator::generate(6, SequenceType::Alphabetic);      // e.g. 'AXQMZB'

UrlUtils::encodeUriComponent('a b');                  // 'a%20b'
UrlUtils::decodeUriComponent('a%20b');            // 'a b'

API

All classes live under the Lacus\Utils namespace.

Class	Method	Description
TypeDescriber	describe(mixed $value): string	Type description for error messages
HtmlUtils	escape, unescape	HTML entity escaping and decoding
SequenceGenerator	generate(int $size, SequenceType $type): string	Random sequence generation
SequenceType	enum: Numeric, Alphabetic, Alphanumeric	Sequence kind
UrlUtils	encodeUriComponent, decodeUriComponent	URI component percent-encoding (RFC 3986)

TypeDescriber::describe()

Same behaviour as JS describeType: null, string, boolean, integer number, float number, NaN, Infinity, Array (empty), number[], (number | string)[], object, resource, etc.

HtmlUtils

• escape(string $value): string — Escapes HTML special characters: & → &, < → <, > → >, " → ", ' → '. Use for safe output and XSS mitigation.
• unescape(string $value): string — Decodes those entities (reverse of escape). Use only on previously escaped or trusted content; decoded output is not safe for direct insertion into HTML.

SequenceGenerator::generate()

• Numeric: digits 0-9
• Alphabetic: uppercase A-Z
• Alphanumeric: 0-9 and A-Z

UrlUtils (URI encoding)

• encodeUriComponent(string $value): string — Percent-encode a string for use as any URI component (path segment, query name/value, or fragment). E.g. a/b → a%2Fb, a b → a%20b.
• decodeUriComponent(string $value): string — Decode a percent-encoded URI component (reverse of encodeUriComponent).
