## 📝 Summary
- What happened.
- PHP 8.5 introduces a built-in URI extension providing standards-compliant parsers for RFC 3986 and the WHATWG URL standard, plus safe mutation APIs.
- Why it matters.
- Replaces ad hoc parsing (e.g., parse_url) that “does not follow any standard” and can cause security issues.
- Key stakeholders.
- The PHP Foundation, Máté Kocsis, PHP internals reviewers, uriparser and Lexbor maintainers, Tideways.
- Risks and tradeoffs.
- Back-compat expectations demanded a careful, year-long design; dependency on upstream libraries requires ongoing coordination.
- Bottom line.
- PHP now ships robust, secure, standards-aligned URL handling, testable in PHP 8.5 RC1.
## 📖 Main Content
- Core arguments
- URLs are deceptively complex; inconsistent parsers lead to bugs and security issues.
- PHP’s legacy parse_url appears to work but is unsafe for malformed/untrusted inputs.
- PHP 8.5’s URI extension implements RFC 3986 and WHATWG URL parsing and provides immutable, component-wise “with-” modifiers.
- Context/definitions
- RFC 3986: the URI standard defining syntax and semantics.
- WHATWG URL: browser-aligned parsing algorithm used on the web.
- Uncertainties
- Migration strategies from parse_url in complex legacy code may vary.
- Future additions under the Uri namespace are planned but unspecified.
### 🗒️ Notes
- “Because things are not as simple as they appear at first glance, these two commonly used standards are incompatible with each other!”
- “parse_url() … does not follow any standard and is explicitly documented not to be used with untrusted or malformed URLs.”
- Example pitfall: example.com/example/:8080/foo yields conflicting host/port/path when using parse_url.
- “Going forward, PHP will include standards-compliant parsers for both RFC 3986 and the WHATWG URL standard … within a new ‘URI’ extension.”
- Normalization vs raw getters: toString vs toRawString.
- RFC process: discussions from June 2024; accepted May 2025 by 30:1 vote.
- Implementation builds on uriparser (RFC 3986) and Lexbor (WHATWG), with upstream contributions to add cloning and component mutation.
- Review by community contributors surfaced and fixed upstream bugs.
- “Fully available for testing with PHP 8.5 RC 1.”

## 🗣️ Paraphrase
- Paragraph A
- URLs look simple but are complex; multiple standards (RFC 3986 vs WHATWG) are incompatible, and mixing parsers creates security risks.
- Paragraph B
- PHP’s new URI extension in 8.5 adds compliant parsers and safe mutation APIs, replacing unsafe parse_url patterns.
## 📰 Newsletter
- PHP 8.5 ships a first-class URI extension with RFC 3986 and WHATWG parsers. Goodbye, gotchas from parse_url—hello, consistency and security. Try it on PHP 8.5 RC1. Bonus: upstream wins in uriparser and Lexbor mean the whole ecosystem benefits. Resources: RFC 3986, WHATWG URL, and PHP 8.5 RC notes. WordPress developers: safer URL handling for plugins, REST endpoints, and redirects is now standard.
## ✅ Action Items
#### DevRel
- Publish migration guide from parse_url to URI extension; record a 10-minute demo.
- Add examples to docs: normalization, raw getters, with-er methods, error handling.
- Host office hours on URL security pitfalls and standards differences.
- Track adoption via code search queries; attribute tutorial-driven installs.
#### OSPO
- Define contribution pathways to upstream (uriparser/Lexbor) and PHP.
- Add license/compliance checks for upstream deps; set review cadence.
- Establish vuln intake and coordinated disclosure playbook with upstreams.
- Maintain SBOM updates for PHP 8.5 builds; set freshness SLOs.
#### Community
- Run “first-issue” sessions for URI tests/docs.
- Publish roadmap clinic notes; encourage component-focused reviews.
- Share sponsor impact reports highlighting upstream fixes.
#### WordPress
- Core: audit parse_url usage; propose phased replacements.
- Core Performance: benchmark URL-heavy routes; set perf budgets.
- Plugins/Themes: provide lints and examples; add provenance checks for redirects.
- Documentation: examples-first patterns and style guide updates.
- Accessibility/Meta: ensure docs have clear, plain-language callouts.
- CLI: add commands/snippets for safe URL mutation; smoke tests.
#### The WPOCC
- Fund microgrants for migrators; stipend maintainers.
- Run documentation sprints; publish migration checklists.
### FAIR
- Require provenance and signatures for upstream libs.
- Publish funding transparency and sunset clauses for programmatic support.
- Offer reusable governance charters and operator agreements.
## 🧪 Hypotheses
- Projects replacing parse_url with the URI extension will reduce URL-related security bugs by ≥50% within a year.
- Normalization defaults will cut duplicate-URL storage by ≥25% in typical apps.
- Availability in core will increase standards-compliant parsing in PHP repos by ≥30% within six months.
- Upstream collaboration shortens bug resolution times by ≥20% compared to bespoke forks.
### 📊 Methodology
- Before/after bug analysis across popular PHP repos (CVE/issue labels).
- Storage dedup assessment on URL datasets with/without normalization.
- Ecosystem code search (e.g., GitHub) for adoption metrics over time.
- Time-to-fix comparisons from upstream issue trackers pre/post-collaboration.
### ❓ Questions
- What’s the recommended migration pattern for ambiguous parse_url outputs?
- How are error states exposed and typed in the new API?
- Any performance tradeoffs vs parse_url under high load?
- How will future URI features integrate under the Uri namespace?
### 🔮 Future Research
- Formal migration tooling (codemods) for parse_url usage.
- Patterns for base-URL resolution aligning with WHATWG in server contexts.
- Security guidelines for user-generated URL inputs at scale.
### 💡 Implications
- Practice: safer redirects, HTTP client configs, and sanitization.
- Policy: org standards mandating URI extension over parse_url.
- Security: reduced SSRF/open redirect classes of bugs.
- Education: curriculum updates on URL standards.
- Funding: demonstrate ROI of upstream-first collaboration.
