Here a function that will natural sort an array by keys with keys that contain special characters.
<?php
function natksort($array)
{
$original_keys_arr = array();
$original_values_arr = array();
$clean_keys_arr = array();
$i = 0;
foreach ($array AS $key => $value)
{
$original_keys_arr[$i] = $key;
$original_values_arr[$i] = $value;
$clean_keys_arr[$i] = strtr($key, "ÄÖÜäöüÉÈÀËëéèàç", "AOUaouEEAEeeeac");
$i++;
}
natcasesort($clean_keys_arr);
$result_arr = array();
foreach ($clean_keys_arr AS $key => $value)
{
$original_key = $original_keys_arr[$key];
$original_value = $original_values_arr[$key];
$result_arr[$original_key] = $original_value;
}
return $result_arr;
}
?>
Hope it will be useful to somebody :)
