HTTP Enums

Fetch PHP provides backed enums under Fetch\Enum.

Method

Method contains GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, TRACE, and CONNECT. Use fromString() to convert a method or tryFromString() to return a fallback. supportsRequestBody() returns true for POST, PUT, PATCH, and DELETE.

ContentType

ContentType includes JSON, URL-encoded form, multipart, text, HTML, XML, binary, PDF, CSV, ZIP, JavaScript, CSS, event stream, NDJSON, and common JSON-based media types (JSON:API, JSON-LD, GeoJSON, and Problem Details).

isJson() recognizes the JSON media type and those JSON-based types. normalizeContentType() returns an enum for a recognized value or preserves an unknown media-type string. Content type parsing is case-insensitive but expects the media type value without parameters.

Status

Status is an integer-backed enum with the HTTP status cases present in the source. Use fromInt() or tryFromInt() and phrase(). Category methods include isInformational(), isSuccess(), isRedirection(), isClientError(), isServerError(), isError(), isCacheable(), isNotModified(), and isEmpty().

For exact response checks, use $response->isStatus(Status::NOT_FOUND). For category checks use $response->successful() or check $response->statusEnum()?->isSuccess().

See the enum reference pages, ContentType, and Status.
