slice_l

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 a substring of length $length of the given string starting at the $offset

namespace HH\Lib\Str;

function slice_l(
  \HH\Lib\Locale\Locale $locale,
  string $string,
  int $offset,
  ?int $length = NULL,
): string;

$offset and $length are specified as a number of characters.

If no length is given, the slice will contain the rest of the string. If the length is zero, the empty string will be returned. If the offset is out-of-bounds, an InvalidArgumentException will be thrown.

See slice() for a byte-based operation.
