How does mysql_drop_db() works?

Explanation

The mysql_drop_db function drop or remove an entire database from the server associated with the specified link identifier.
Syntax

bool mysql_drop_db ( string database_name [, resource link_identifier])

Returns TRUE on success or FALSE on failure.
mysql_drop_db() attempts to drop (remove) specified database from the server. The database to be dropped is passed as argument inside 'mysql_drop_db' function.
Example

<?php

//Attempt to connect to the default database server

$link = mysql_connect("mysql_host", "mysql_user", "mysql_password")
or die ("Could not connect");
$result= mysql_drop_db("my_database");
if ($result) {
echo "Database my_database was successfully droppedn";
}else {
echo 'Error dropping database: ' . mysql_error() . "n";
}
mysql_close($link);
?>

In the above example, connection to the default database server is established. The database 'my_database' to be dropped is passed as an argument to the function 'mysql_drop_db' function. After successful execution of this function the database will be dropped or removed from the server.
This function is deprecated, it is preferable to use mysql_query() to drop the database instead of 'mysql_drop_db' function.
Example:

<?php

//Attempt to connect to the default database server

$link = mysql_connect("mysql_host", "mysql_user", "mysql_password")
or die ("Could not connect");
$qry="drop database my_database";
$result= mysql_query($qry,$link);
if ($result) {
echo "Database my_database was successfully droppedn";
}else {
echo 'Error dropping database: ' . mysql_error() . "n";
}
mysql_close($link);
?>
