PHP5 - I want to write a Hindi text on image

Question

I want to write Hindi text on an image using PHP.

This is my code:

$im = @imagecreate(210, 50);
$background_color = imagecolorallocate($im, 255, 255, 255); 
$text_color = imagecolorallocate($im, 0, 0, 0); 
imagestring($im, 7, 15, 15, utf8_encode("पुलिसवाला आमिर खान..."), $text_color);
ImagePNG($im, 'a.png'); 
imagedestroy($im);

Can someone help me do this?
