Note Submitter: fight4freedom2-live at yahoo dot com ---- If you've run other versions of PHP in the past and are having trouble upgrading to PHP5, particularly in loading the dynamic link library 'php_mysql.dll' (despite following all the guidance in this documentation), try the following: 1.) REMOVE old copies of 'libmysql.dll' from your WINDOWS and WINDOWS\system32 folders (check BOTH places). 2.) Verify that your System Path is correctly configured to search the 'C:\PHP5' and 'C:\PHP5\ext'. To do this on WinXP, go to your Control Panel, open System, click Advanced tab, click on Environment Variables, under (lower pane) 'System variables', select 'Path', and then click Edit. Your system path should look something like: %SystemRoot%\system32;%SystemRoot%; C:\Program Files\MySQL\MySQL Server 4.1\bin;C:\PHP5;C:\PHP5\ext; Because the system path checks the Windows and System32 folders for dll's *before* checking the PHP folder, old copies of php_mysql.dll will load up first and foul your PHP initialization if you don't remove them.
