A PHP library for parsing CSS files into a manipulable data structure and outputting optimized CSS.
PHP CSS Parser is a library written in PHP that parses CSS files into a structured, object-oriented data model. It allows developers to programmatically read, analyze, modify, and output CSS, enabling dynamic stylesheet generation and manipulation within PHP applications.
PHP developers who need to programmatically process CSS, such as those building CSS preprocessors, optimization tools, dynamic style generators, or CMS themes.
It provides a complete, standards-aware CSS object model in pure PHP, with a detailed API for manipulation and formatting, making it a reliable foundation for CSS-related tooling without external dependencies.

Parses CSS into a detailed object model including at-rules, selectors, and values, as evidenced by the extensive structure dumps in the README examples like the @font-face and @keyframes handling.
Offers multiple output formats via the OutputFormat class, allowing for compact, pretty, or custom CSS generation, demonstrated in the render() method with options like indentWithSpaces(4).
Handles a wide range of at-rules such as @charset, @font-face, and @keyframes, enabling complex stylesheet manipulations, shown in the example parsing and outputting @font-face and @keyframes blocks.
Provides methods like getAllDeclarationBlocks() and getAllValues() for easy access to CSS elements, simplifying common manipulation tasks as illustrated in use cases like prepending IDs to selectors.
The README admits that real multibyte support is lacking in the 'To-Do' list, with only partial handling for charsets like UTF-8, which can hinder processing of internationalized stylesheets.
From the 'To-Do' list, features like named color support and more convenience methods are not implemented, making it less suitable for projects using the latest CSS specifications without workarounds.
Parsing can be slow for large files, and disabling multibyte functions for speed is not recommended for untrusted input, indicating potential bottlenecks in high-throughput scenarios.
Manipulating CSS requires navigating a deep object model (e.g., CSSList, RuleSet), which can be overkill for simple edits compared to string-based approaches, adding cognitive overhead.
