I'm making a web in Vietnamese. My DB stores data in UTF-8 format. But I need to convert it no
NCR format and I wrote a function for this problem.
// Convert a string from UTF-8 format to NCR format for all language
// Use first character and up to 5-next characters

function utf8_to_ncr($utf8)
{
$len = strlen($utf8);
$ncr = ""; $i = 0;
while ($i < $len)
{
$code = 0;
$unit = ord($utf8[$i]);
if ($unit < 0x80)
{
$code = $unit;
$next = 0;
}
elseif ($unit < 0xE0)
{
$code = $unit & 0x1F;
$next = 1;
}
elseif ($unit < 0xF0)
{
$code = $unit & 0x0F;
$next = 2;
}
elseif ($unit < 0xF8)
{
$code = $unit & 0x07;
$next = 3;
}
elseif ($unit < 0xFC)
{
$code = $unit & 0x03;
$next = 4;
}
elseif ($unit < 0xFE)
{
$code = $unit & 0x01;
$next = 5;
}
for ($j = 0; $j < $next; $j++)
{
$i++;
$unit = ord($utf8[$i]);
$code = ($code << 6) | ($unit & 0x3F);
}
if ($code < 0x80)
{
$ncr .= chr($code);
}
else
{
$ncr .= "&#" . $code . ";";
}
$i++;
}
return $ncr;
}
