- How do I install voku/simple_html_dom in a Laravel application?
- Install it with composer require voku/simple_html_dom; it is a framework-agnostic PSR-4 package with no Laravel service provider, so it drops into any Laravel version running a supported PHP. Check your composer.json PHP floor against the package constraint, since recent releases target PHP 8.x while older tags still support PHP 7.1. Laravel 9, 10 and 11 on PHP 8.1+ is the comfortable band, and the only system requirements are ext-dom and ext-mbstring. Add voku/portable-utf8 if you need fixed UTF-8 output.
- Does voku/simple_html_dom have a Laravel service provider or facade?
- No. The package ships no service provider, facade or package auto-discovery, which is what keeps it free of framework coupling. If you want dependency injection, write a small service provider yourself of roughly fifteen lines that binds an HtmlParserContract interface to an implementation wrapping HtmlDomParser. That single indirection also turns the dependency into something swappable later.
- How do I extract elements with jQuery-style selectors using voku/simple_html_dom?
- Create a document with HtmlDomParser::str_get_html() or HtmlDomParser::file_get_html(), then call find() with CSS selectors such as 'div.item a' to get nodes back. Each node exposes text, innertext and attribute helpers, and in v5 nested find() calls return live nodes scoped to the original DOM, so mutations update the source document. This is the library's main strength over plain querying libraries.
- voku/simple_html_dom vs symfony/dom-crawler: which should I use in Laravel?
- symfony/dom-crawler is first-party maintained and is the lower-risk default if you only need querying with CSS selectors. voku/simple_html_dom's advantage is jQuery-style manipulation with live node mutation, plus an API that stays largely source-compatible with the legacy simplehtmldom parser. A pragmatic answer is to define an interface and bind one of them, so you can benchmark both on real fixtures before committing.
- Does voku/simple_html_dom handle UTF-8 and invalid or broken HTML?
- Yes. UTF-8 support is built in and can be strengthened with voku/portable-utf8, and partially invalid HTML is tolerated because parsing goes through DOMDocument rather than string manipulation. Be aware that malformed markup often yields a partial DOM instead of throwing an exception, and libxml warnings are commonly suppressed. That silent-failure behaviour is exactly why golden-file regression tests on real documents matter more than happy-path unit tests.
- Is voku/simple_html_dom safe for parsing untrusted user-supplied HTML?
- DOMDocument-based parsing of user input requires deliberate configuration around entity expansion and external entities. The library mitigates much of the classic risk, but you should still add explicit tests for XXE and billion-laughs style payloads before parsing anything users control. Treat the parser as an ingestion tool for semi-trusted sources, not as a sanitization layer, and use HTMLPurifier or symfony/html-sanitizer when you need safe output.
- How should I test HTML parsing with voku/simple_html_dom?
- Use PHPUnit with golden-file fixtures: store representative real-world HTML documents and assert that the extracted values match expected output. Because malformed HTML can silently produce a partial DOM, explicitly test failure modes and encoding edge cases rather than only well-formed markup. If any user-supplied HTML reaches the parser, add malicious entity payloads to the suite as well.
- Is voku/simple_html_dom still maintained, and which PHP versions does it support?
- It is actively maintained with GitHub Actions CI and is tested on PHP 7.1 through 8.4, with recent releases targeting PHP 8.x. However, the project has a single primary maintainer and traces its lineage to an abandoned SourceForge project, so budget for a possible internal fork. Verify current release activity and Packagist download volume before committing long term.
- Can I migrate from sunra/php-simple-html-dom-parser or legacy simplehtmldom to voku/simple_html_dom?
- Largely yes. voku/simple_html_dom deliberately retains the legacy jQuery-like API, so migration is mostly a namespace replacement plus removal of deprecated calls rather than a rewrite. The engine underneath changed to ext-dom and Symfony CssSelector, so re-run your fixture tests after switching. Expect some non-idiomatic PHP 8 signatures inherited from the legacy API and gate them with static analysis.
- What are the performance and memory limits of voku/simple_html_dom on large documents?
- Parsing goes through DOMDocument, so whole documents are loaded into memory and very large pages will hit memory limits unless you chunk or stream at the HTTP layer. Define a maximum document size and throughput target before rollout and enforce them in your ingestion jobs. For high-volume work, benchmark the library against symfony/dom-crawler on your own fixtures to confirm it meets the budget.
