PHP 5 Beta 1 - mysql 4.0.12 error: "Fatal error: Call to undefined function: mysql_connect() in D:\pub\mysqltest.php on line 6"

I have just recently installed PHP beta 5 on Windows XP Pro and I am having problems connecting to mysql, phpinfo() works fine but it looks as though it is not loading any mysql modules even though PHP install file says this is now built in.When I run attached mysql connect test I get error "Fatal error: Call to undefined function: mysql_connect() in D:\pub\mysqltest.php on line 6" I have trawled through various news groups and though I have seen similar problems but they all seem to be with any flavour except windows XP, so I would like to know if there is anybody who could give me, a newbie, a point in the right direction as this is driving me crazy. Do I have to tell PHP where to look for MySQL? tks in advance regards jeremy --
