There are no open bug reports for array_search(). Loads of bogus ones though.
array_search() also completely the wrong tool for the job - the code
you posted is much more complicated and slower than it needs to be.
That whole palaver that you go through to produce $reduced could be
replaced with:
$reduced = array_merge(array(), array_unique($str));
That nested loop you use to produce $final would be rather simpler and
faster if you just flipped $reduced and used a hash lookup.
$charmap = array_flip($reduced);
foreach ($str as $char) { $final[] = $charmap[$char]; }
