Yet another MySQL+PHP5 issue

I am running PHP 5.0.2 and MySQL 4.0.21-nt the install directory (C:\WBP\PHP\) is in the path. The MySQL dir is not in the path. I am attempting to use the PHP shell/command line feature (rather than web server), however I get this result: ----------------------------------------------------------------- C:\> php -v PHP Warning: PHP Startup: Unable to load dyanamic library './php_mysql.dll' - The specified module could not be found. ----------------------------------------------------------------- This occures with libmysql.dll in either the php dir, %WINDIR% and %WINDIR%\system32. If I place it in any of these spots and rename it php_mysql.dll, I get this error: ----------------------------------------------------------------- PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'php_mysql.dll' in Unknown on line 0 ----------------------------------------------------------------- Someone said that this file does not work for MySQL 4.0.21, is that the cause of this problem (or set of problems) or should I look further? I'm really stumped here. Thank you, -Jim Stapleton
