encoding

This is how you can encode the values of an multidimensional array using two functions. You could of course optimize it to one, by moving the mb_convert_encoding-function into the first condition of the convert2encodingRecursive-function. But in my case I needed the string converter as well.

If you have trouble storing åäö in a UTF-8 mysql database.
make sure field, table and database is utf8_general_ci
Check mysql varaibles by running the following mysql command:

Writing an RSS feed based on HTML can cause some trouble using htmlentities though it converts too much, use htmlspecialchars instead.

First: The utf8_function function converts from ISO 8859-1 to UTF-8. So you only need this function, if your input encoding/charset is ISO 8859-1. But why don’t you use UTF-8 in the first place?

Second: You don’t need htmlentities. You just need htmlspecialchars to replace the special characters by character references. htmlentities would replace “too much

Have not tested it...

function check_utf8($str) {
$len = strlen($str);
for($i = 0; $i < $len; $i++){
$c = ord($str[$i]);
if ($c > 128) {
if (($c > 247)) return false;
elseif ($c > 239) $bytes = 4;
elseif ($c > 223) $bytes = 3;
elseif ($c > 191) $bytes = 2;
else return false;
if (($i + $bytes) > $len) return false;
while ($bytes > 1) {
$i++;
$b = ord($str[$i]);
if ($b < 128 || $b > 191) return false;

<?php
// Fixes the encoding to uf8
function fixEncoding($in_str)
{
  $cur_encoding = mb_detect_encoding($in_str) ;
  if($cur_encoding == "UTF-8" && mb_check_encoding($in_str,"UTF-8"))
    return $in_str;
  else
    return utf8_encode($in_str);
} // fixEncoding 
?>
