request_input

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Return the input handle for the current request

namespace HH\Lib\IO;

function request_input(): ReadHandle;

In CLI mode, this is likely STDIN; for HTTP requests, it may contain the POST data, if any.

This MAY be a CloseableReadFDHandle.

Returns

• ReadHandle
