Answer 1

echo strrev("String"); //gnirtS
As for UTF-8 ( echo strrev("Строка"); //�коЀтѡ�), you can play with the encoding:

function str_reverse($string){
   return iconv('utf-16be', 'utf-8', strrev(
      iconv('utf-8', 'utf-16le', $string)
   ));
}

or directly in the forehead:

function str_reverse($string){
   return implode("", array_reverse(
      str_split($string)
   ));
}
