If a database is no longer required then it can be deleted forever. You can use pass an SQL command to
mysql_query to delete a database.
Example:
Try out following example to drop a database.
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
$sql = 'DROP DATABASE test_db';
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
die('Could not delete database db_test: ' . mysql_error());
}
echo "Database deleted successfully\n";
mysql_close($conn);
?>

WARNING: its very dangerous to delete a database and any
table. So before deleting any table or database you should make sure you
are doing everything intentionally.
Deleting a Table:
Its again a matter of issuing one SQL command through
mysql_query
function to delete any database table. But be very careful while using
this command because by doing so you can delete some important
information you have in your table.
Example:
Try out following example to drop a table:
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
$sql = 'DROP TABLE employee';
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
die('Could not delete table employee: ' . mysql_error());
}
echo "Table deleted successfully\n";
mysql_close($conn);
?>
