could_include

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.

Returns whether the (php) file could be included (eg if its been compiled into the binary)

namespace HH;

function could_include(
  string $file,
): bool;

This is useful when you don't have a filesystem (RepoAuthoritative mode) but still want to know if including a file will work.

  • string $file

Returns​

  • bool
