This is only documented in the migration guide[1] so far:

| The needle argument for mb_strpos(), mb_strrpos(), mb_stripos(),
| mb_strripos(), mb_strstr(), mb_stristr(), mb_strrchr() and
| mb_strrichr() can now be empty.

Description:
------------
php < 8:
  var_dump(false === mb_stripos('123456789', ''));
Result:
  <br />
  <b>Warning</b>:  mb_stripos(): Empty delimiter in <b>[...][...]</b> on
line    <b>4</b><br />
  bool(true)

php 8:
  var_dump(false === mb_stripos('123456789', ''));
Result:
  bool(false)

In versions lesser than 8 it will throw a warning but return true, which is totally opposite to
version 8 result
