This question already has an answer here:
Please help me to write full code in php and sql to update only (point) in table below.
table name : tuser
id_user : 12
name : lisa
username : lisa1990
password : User123
point : 12930
</div>
It is very easy...
$con = mysql_connect("servername","username","password");
mysql_select_db("databasename");
$command = "UPDATE tuser SET point='your value' where id=whatever";
//replace 'your value' with the new value and "whatever" with the user id
mysql_query($command);
mysql_close_connection($con);
Next time don't ask so stupid questions here... use Google
