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.

): string;

See Str\trim_l() for more details.

  • To strip from both ends, see Str\trim_l().
  • To only strip from the right, see Str\trim_right_l().
  • To strip a specific prefix (instead of all characters matching a mask), see Str\strip_prefix_l().
