note 89688 modified in function.utf8-encode by danbrown

This function may be useful do encode array keys and values [and checks first to see if it's already in UTF format]: <?php public static function to_utf8($in) { if (is_array($in)) { foreach ($in as $key => $value) { $out[to_utf8($key)] = to_utf8($value); } } elseif(is_string($in)) { if(mb_detect_encoding($in) != "UTF-8") return utf8_encode($in); else return $in; } else { return $in; } return $out; } ?> Hope this may help. [NOTE BY danbrown AT php DOT net: Original function written by (cmyk777 AT gmail DOT com) on 28-JAN-09.] --was-- The function from cmyk777 at gmail dot com does not work if the string ists already in UTF8 so I add a check before convert public static function to_utf8($in) { if (is_array($in)) { foreach ($in as $key => $value) { $out[to_utf8($key)] = to_utf8($value); } } elseif(is_string($in)) { if(mb_detect_encoding($in) != "UTF-8") return utf8_encode($in); else return $in; } else { return $in; } return $out; } Hope this may help. http://php.net/manual/en/function.utf8-encode.php
