HH\Lib\Str\contains_ci

This API is part of the Hack Standard Library, not HHVM itself.

Returns whether the "haystack" string contains the "needle" string (case-insensitive)

namespace HH\Lib\Str;

function contains_ci(
  string $haystack,
  string $needle,
  int $offset = 0,
): bool;

An optional offset determines where in the haystack the search begins. If the offset is negative, the search will begin that many characters from the end of the string. If the offset is out-of-bounds, a ViolationException will be thrown.

Parameters

  • string $haystack
  • string $needle
  • int $offset = 0
