For deleting data from a table, you can again use the same mysql_query function. You need to pass MySQL delete query in this function.
Example:
<?php $query = "delete from employees where id = 3"; $result = mysql_query($query, $con); if(!$result) { die("Error deleting data",mysql_error()); } echo "Data deleted successfully"; ?>
You can use all the other SQL queries using mysql_query() function to perform different operations.
