First I compiled PHP with the Mysql and Apache Module, and it worked.
then I have uninstalled it and recompiled it again and configured it like this:
./configure --with-mysql --with-db2 --with-apache=../apache_1.3.9 --enable-track-vars

But now I can`t connect to a mysql Database. The connection to the mysql Server seems to work.
my php command line looks like this:
<?php mysql_connect ("localhost:3306","root","mypassword");
$result = mysql_db_query ("ubr", "select * from persdat");
while($row = mysql_fetch_array($result))
	{
		echo $row["user-id"];
		echo $row["fullname"];
	}
mysql_free_result($result);
?>
(modified query from the php manual).
This Query returns "The Document contains no Data" at my Browser.
