I've tested this extensively on PHP v4.2.1 and Apache v1.3.26...

can't get the function, mysql_select_db(), to work from within a user defined
function...
 
e.g. file "functions.php"...

include("config.php"); // database name etc.
$db = ("mydb");
    mysql_connect($hostname, $user, $pass) OR DIE("Unable to connect to database");
    
/* if you included the following code WITHIN the function, it won't work. It works as long as it's placed before the start of the function: */

mysql_select_db($db);

/* and here's the function */

function adminstuff() {

//    $result = mysql_query('SELECT uid, uname FROM users');
//   $resultrow = mysql_fetch_array($result);
//	return array ($resultrow[0], $resultrow[1]);

/* Select all users with the preference Apples */
$query = "SELECT * FROM users";

$result = MYSQL_QUERY($query);

/* How many of these users are there? */
$number = MYSQL_NUMROWS($result);
END---


The error returned is:
Warning: mysql_numrows(): supplied argument is not a valid MySQL result resource in /functions.php on line 40

If one adds an OR DIE command to the end of the mysql_select_db() function, this is where the script halts.

This code was running on ipowerweb.com web hosting servers, so I don't have access to gbd and all the technical gumf.
