print_r($ar);
  foreach($ar as $k=>$v) {
    if(substr($v,0,2) == "%u")
      $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,-4)));
    elseif(substr($v,0,3) == "&#x")
      $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));

Hello;

I need this convert to use in my web sms service , couse the company which I am deailing with I have to vivst there web to make the convert to the string the copy it to my web page then send it...

so What I want to make my own convertor.

so I tried this :

<?
 
 
function utf8toucs2hex($utf8)
{
 $utf8_hex = bin2hex( $utf8 );
 return utf8toucs2($utf8_hex);
}

function utf8hextoucs2hex($str)
{
       $ucs2 = "";

       for ($i=0;$i<strlen($str);$i+=2)
       {
                $char1hex = $str[$i].$str[$i+1];
              
  $char1dec = hexdec($char1hex);
                if ( $char1dec < 128)
  {
                        $results = $char1hex;
  }
                else if ( $char1dec < 224 )
                {
                 $char2hex = $str[$i+2].$str[$i+3];
                        $results = dechex( ((hexdec($char1hex)-192)*64) + (hexdec($char2hex)-128) );
                        $i+=2;
                }
                else if ( $char1dec < 240 )
                {
                 $char2hex = $str[$i+2].$str[$i+3];
                 $char3hex = $str[$i+4].$str[$i+5];
                        $results = dechex( ((hexdec($char1hex)-224)*4096) + ((hexdec($char2hex)-128)*64) + (hexdec($char3hex)-128) );
                        $i+=4;
                }
  else
  {
   //Not supported: UCS-2 only
                        $i+=6;
  }

  while ( strlen($results) < 4 )
  {
   $results = '0' . $results;
  }

                $ucs2 .= $results;
        }

        return $ucs2;
}

 $error="";
 if (isset ($_POST['submit']) && !empty($_POST['Mobile'])&& !empty($_POST['msg'])) {
$user = "username";
$password = "password";
$api_id ="apID";
$baseurl ="http://api.clickatell.com";
$text =$_POST['msg'];
$message_unicodehex = utf8toucs2hex($text);
$to = $_POST['Mobile'];
// auth call
$url = "$baseurl/http/auth?user=$user&password=$password&api_id=$api_id&unicode=1";
// do auth call
$ret = file($url);
$from="QN";
// split our response. return string is on first line of the data returned
$sess = split(":",$ret[0]);
if ($sess[0] == "OK") {
$sess_id = trim($sess[1]); // remove any whitespace

$url = "$baseurl/http/sendmsg?session_id=$sess_id&to=$to&text=$message_unicodehex&from=$from";
// do sendmsg call
$ret = file($url);
$send = split(":",$ret[0]);
if ($send[0] == "ID")
$error="success
message ID: ". $send[1];
else
$error='send message failed <br>check the mobile number format to be without + and without 00 ( 9746026267)';
} else {
$error="Authentication failure: ". $ret[0];
exit();
}
}
else $error="Plz Fill All the fields";
?>

So when I try the string in english it return to me the same string when I use there convertor. it works the same as there convertor , but if I put an arabic string my convertor gives defferent one then there convertor result...

what can I do?

Hello All;

I have solved the problem and make that function of convertor:

function sms__unicode($message) {
  if (function_exists('iconv')) {
    $latin = @iconv('UTF-8', 'ISO-8859-1', $message);
    if (strcmp($latin, $message)) {
      $arr = unpack('H*hex', @iconv('UTF-8', 'UCS-2BE', $message));
      return strtoupper($arr['hex']) .'&unicode=1';
    }
  }
  return FALSE;
}

It works great with arabic unicoding .....
