Oihana PHP Http

Composable PHP HTTP toolkit. Part of the Oihana PHP ecosystem, this package provides battle-tested helpers for HTTP-facing code: client IP detection against reverse proxies, GDPR-compliant anonymisation, typed Set-Cookie builders and parsers, PSR-7 authentication and request inspection helpers, content negotiation, HTTP dates, URL/query string toolkit, HMAC signatures for signed URLs and webhooks, User-Agent parser. PSR-7 compatible, zero magic strings.

📦 Installation

Requires PHP 8.4+. Install via Composer:

✨ What you can do

Network & IP

• Detect the real client IP behind a chain of trusted reverse proxies. Walks X-Forwarded-For right-to-left, skips trusted hops via CIDR matching, falls back on Forwarded (RFC 7239), X-Real-IP and REMOTE_ADDR. Validates IPv4 and IPv6, normalizes IPv4-mapped IPv6, strips IPv6 zone IDs.
• Anonymise IPs for GDPR-friendly logging — truncateIpToSlash24() (IPv4 → /24), truncateIpToSlash48() (IPv6 → /48, BfDI/BSI recommendation), or anonymizeIp() for a single entry point routing by address family.

Cookies

• Build & parse Set-Cookie / Cookie headers with strict validation (rejects CRLF injection, control characters, malformed names). Typed attributes: HttpOnly, Secure, SameSite=Strict|Lax|None, Domain, Path, Max-Age, Expires (RFC 7231 IMF-fixdate), Priority (Low|Medium|High), Partitioned (CHIPS).

Auth & PSR-7 request inspection

• Authorization helpers — parseAuthorizationHeader(), getBearerToken(), getBasicAuth() (RFC 7617 split on first colon).
• Request inspection — wantsJson(), isAjax(), isHttpsRequest() (with anti-spoofing trusted-proxy filter symmetric with getClientIp()).

Content negotiation

• *`Acceptparser** —parseAcceptHeader()is a single universal parser forAccept,Accept-LanguageandAccept-Encoding` (same RFC 7231 §5.3 grammar). Returns entries sorted by q-value, stable on ties.
• negotiate() — best-match selection with wildcard support (*, */*, type/*), case-preserving candidate return.
• parseContentType() — {type, charset, boundary, params} tuple, case-insensitive on type/charset, case-preserving on boundary.

Dates, URLs, signatures

• HTTP dates — parseHttpDate() accepts all three RFC 7231 §7.1.1.1 formats (IMF-fixdate, RFC 850, asctime); formatHttpDate() emits IMF-fixdate from any DateTimeInterface converted to UTC.
• URL & query string toolkit — parseQueryString() / buildQueryString() preserve duplicates, withQueryParams() / removeQueryParam() immutable PSR-7 updates, normalizeUrl() canonical form, isAbsoluteUrl(), getHost() normalised host extraction, isPublicUrl() / isLocalUrl() (local / private / reserved host detection), withUrlComponents() derive a URL by replacing/removing components.
• HMAC signatures — signUrl() / verifySignedUrl() for pre-signed URLs with TTL; verifyHmacSignature() for webhook payload verification (Stripe / GitHub / Slack / Mailchimp).

User-Agent

• Pragmatic, dependency-free parser — parseUserAgent() returns a structured UserAgentInfo DTO (browser, OS, device class, bot flag). Predicates isBotUserAgent() and isMobileUserAgent() for the common one-shot questions.

Under the hood

• Consistent typed enums and constants — CookieAttribute, CookieOption, CookiePriority, SameSite, SetCookieField, AcceptField, ContentTypeField, AuthorizationField, BasicAuthField, BrowserName, OsName, SignatureFormat, SignedUrlField.
• Pure PSR-7 — no framework lock-in. Works with Slim, Laravel, Symfony HTTP Foundation (via PSR-7 bridge), Hyperf, RoadRunner, etc.
• Strongly-typed enums and constants — no magic strings anywhere.
• Constant-time HMAC comparisons (hash_equals()) — safe against timing-side-channel attacks.
