String
This project is a PHP utility library that provides an object-oriented interface for handling textual data. It serves as a framework for consistent string manipulation, offering tools to process bytes, UTF-8 code points, and grapheme clusters through a unified set of classes.
The library distinguishes itself by implementing a lazy evaluation system that defers expensive string computations until the moment they are accessed, which helps optimize memory usage and application responsiveness. It also features polymorphic input normalization, which automatically detects character encoding to instantiate the appropriate handler for either raw binary or UTF-8 text.
The toolkit covers a broad range of data processing capabilities, including locale-aware transliteration for generating URL-friendly slugs and a rule-based engine for dynamic word inflection. It supports common text operations such as casing transformations, secure token generation, and length truncation, all while maintaining awareness of multi-byte characters and combined symbols.
Features
- Text Processing Utilities - Provides a comprehensive object-oriented toolkit for text manipulation, including inflection, casing, and truncation.
- Textual Data Processing - Provides a unified object-oriented interface for manipulating strings, bytes, and grapheme clusters.
- Object-Oriented Wrappers - Encapsulates primitive strings within class instances to provide a unified, object-oriented interface for text manipulation.
- UTF-8 Byte Operations - Standardizes raw input by handling UTF-8 encoding, byte sequences, and grapheme clusters through a unified interface.
- Text Cleaning Utilities - Converts arbitrary text into URL-friendly slugs by mapping locale-specific characters and handling special symbols.
- String Processing Optimizations - Defers expensive string computations until access to optimize memory usage and application responsiveness.
- Grapheme-Aware Processing - Provides grapheme-aware text processing to correctly handle multi-byte characters and combined symbols.
- Lazy Evaluators - Implements lazy evaluation to defer expensive string computations until the moment they are accessed.
- Text Case Transformations - Transforms text between various casing formats using locale-aware rules to maintain consistent naming conventions.
- Transliteration Utilities - Provides locale-aware transliteration to map complex character sets to ASCII equivalents for consistent identifiers.
- Lazy String Processing - Implements a lazy evaluation system that defers string generation until the moment of access.
- Lazy String Processors - Defers string generation logic using callbacks to avoid unnecessary computation for unused data.
- Polymorphic Normalizers - Automatically detects character encoding to instantiate the appropriate handler for raw binary or UTF-8 text.
- Linguistic Rule Engines - Applies linguistic patterns and exception dictionaries to dynamically transform word forms between singular and plural states.
- Command String Generators - Generates strings only when accessed by storing values as callbacks to avoid unnecessary computation.
- Polymorphic String Normalizers - Instantiates the correct string object type automatically by detecting whether input is valid UTF-8 or raw bytes.
- Word Form Converters - Converts words between singular and plural forms using language-specific rules to ensure grammatical correctness.
- Slug Generators - Transforms arbitrary text into URL-friendly slugs using locale-aware transliteration rules.
