I have found multiple sites with the above solutions, plus gobs more about copying .dll’s and .ini’s back and forth from the php/ext dir, mysql/bin dir, and winnt/dir. Still no go. Apache error.log says nothing is wrong, and I am able to do all of my other PHP and MySQL fine on my local server. Queries all work, etc. The only thing that doesn’t work is WP. So maybe someone sees a problem with my test.php output:
