Is this a valid PHP function call?

Code: Select all

function connectToDB(&$errorMessage = "" )
{

$link = mysql_connect( ... )

if (! $link) $errorMessage = "Failed to connect to mysql";

}


connectToDB();

Gah, I stupidly post in the wrong forum. Can someone help to move the post? Apologies in advance!

I'd only make one modification; Try instead of
...
if ($link) $errorMessage = "Failed";
...
Something like this:

if (!$link) return false;
else return true;

This way, you could do something like this:
$x = connectToDB();
if (!$x){echo("Failed! Help!");}

Best of coding,
