Storing and displaying unicode string (हिन्दी) using PHP and MySQL

Did you set proper charset in the HTML Head section?

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

or you can set content type in your php script using -

   header( 'Content-Type: text/html; charset=utf-8' ); 

There are already some discussions here on StackOverflow - please have a look

So what i want to know is how can i directly store सूर्योदय into my database and fetch it and display in my webpage using PHP.

I am not sure what you mean by "directly storing in the database" .. did you mean entering data using PhpMyAdmin or any other similar tool? If yes, I have tried using PhpMyAdmin to input unicode data, so it has worked fine for me - You could try inputting data using phpmyadmin and retrieve it using a php script to confirm. If you need to submit data via a Php script just set the NAMES and CHARACTER SET when you create mysql connection, before execute insert queries, and when you select data. Have a look at the above posts to find the syntax. Hope it helps.

** UPDATE **Just fixed some typos etc

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"><?php $con = mysql_connect("localhost","root","");if (!$con)  {  die('Could not connect: ' . mysql_error());  }mysql_query('SET character_set_results=utf8');mysql_query('SET names=utf8');mysql_query('SET character_set_client=utf8');mysql_query('SET character_set_connection=utf8');mysql_query('SET character_set_results=utf8');mysql_query('SET collation_connection=utf8_general_ci');mysql_select_db('onlinetest',$con);$nith = "CREATE TABLE IF NOT EXISTS `TAMIL` (  `data` varchar(1000) character set utf8 collate utf8_bin default NULL) ENGINE=InnoDB DEFAULT CHARSET=latin1";if (!mysql_query($nith,$con)){  die('Error: ' . mysql_error());}$nithi = "INSERT INTO `TAMIL` VALUES ('இந்தியா நாட்டின் பக்கங்கள்')";if (!mysql_query($nithi,$con)){  die('Error: ' . mysql_error());}$result = mysql_query("SET NAMES utf8");//the main trick$cmd = "select * from TAMIL";$result = mysql_query($cmd);while($myrow = mysql_fetch_row($result)){    echo ($myrow[0]);}?></body></html>

For those who are looking for PHP ( >5.3.5 ) PDO statement, we can set charset as per below:

$dbh = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
