A MySQL PHP update query example

Nothing major here, just an example MySQL PHP UPDATE query (really, a PHP SQL UPDATE query example that happens to use a MySQL database). For all the things I've done lately with PHP, I think this is the first PHP update query I've written, and I wanted to put an example out here so I can find it easily later.

So, with no further ado, here is a simple MySQL PHP update query example:

// connect to the mysql database
$link = mysql_connect('localhost', 'USERNAME', 'PASSWORD');
if (!$link) 
{
  die('Could not connect: ' . mysql_error());
}

// select our mysql database name
mysql_select_db ('drupal');

// i'm skipping all my Node work here.
// suffice it to say i have a node object i'm working with.

$t = time();

// execute the php update query
$query = "update node set changed=$t where nid=$node->nid";
mysql_query($query);

// all done, shut 'er down
mysql_close($link);

FWIW, this PHP update query example was created to work with a Drupal database, and that's where the "node" database table comes from.
