Well, I found the answer here: [url=http://www.notestips.com/80256B3A007F2692/1/TAIO-64MEGD]http://www.notestips.com/80256B3A007F2692/1/TAIO-64MEGD[/url] It was nothing obvious.  Once I'd moved the file libmysql.dll from the \php directory to \Apache2\bin  -  connectivity!

OK, found this: [url=http://www.devshed.com/c/a/MySQL/Performing-Basic-Tasks-with-MySQL-4-and-Above-using-mysqli-with-PHP-5/]http://www.devshed.com/c/a/MySQL/Performing-Basic-Tasks-with-MySQL-4-and-Above-using-mysqli-with-PHP-5/ [/url] I'll let you know if it leads me anywhere.

I don't know.  I've never installed or used php5 before so I'm totally in the dark.  I don't even know what the 'mysqli libraries' are.  I'll have a google and see what I can find but I don't even know what the question is that I should be asking.  :-\

I have just upgraded MySQL from 4.0 to 4.1 and moved the data onto another disk.  It is running on its own without problems. I have also updated to PHP5 and it is also running on my Apache 2.2 server without problems. I cannot get MySQL to work with php5.  I have followed all the instructions at php.net, eg updated the PATH, extension_dir and uncommented the mysql extension so it will load.  I have checked and the dll is in the path specified.  However attempts to connect to MySQL still fail without error.  Is there is there an exhaustive checklist somewhere I could check, or could some kind soul walk me through it so I can locate what is going wrong. Any help would be appreciated.
