HH\Lib\Str\contains_ci

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.

• To search for the needle case-sensitively, see Str\contains().
• To get the position of the needle case-insensitively, see Str\search_ci().
