Last day one of my friend came to me.He was facing a problem (he solved later).Here is his problem –
The Bangla/Unicode data become ?????? in his page.

I’m gonna tell u today step-by-step what u need to do if u wanna develop Bangla/Unicode based Web App.

#1 . First make the database with CHARACTER utf8 and collation_connection =’utf8_general_ci’
#2 . Make the Tables with same configuration.
#3 . When u connect the database use following 2 lines just below the mysql_select_db()

mysql_query(’SET CHARACTER SET utf8′);
mysql_query(”SET SESSION collation_connection =’utf8_general_ci’”);

#4 . Set the META-TAG as “Content-Type: text/html; charset=UTF-8″

Thats it u r done.Here is a sample page what will show data from database

<?
header(’Content-Type: text/html; charset=UTF-8′); //As its php page i dont need the meta-tag so i need to send a header .

mysql_connect(’localhost’,'xxxxx’,'xxxxxx’) or die(’Error In connection’);
mysql_select_db(’test’) or die(’Error In connection(DB)’);

mysql_query(’SET CHARACTER SET utf8′);
mysql_query(”SET SESSION collation_connection =’utf8_general_ci’”);

$re = mysql_query(”SELECT * FROM test”) or die(’Query Problem’);
while($row = @mysql_fetch_assoc($re))
echo $row['name'].PHP_EOL;
?>
