Same, my windows machine won't recognize. These are the things I have done:
Installed apache 2.055 / PHP 5.1.2
Configured httpd.conf according to php's install.txt
uncommented php.ini's mysql extension.
made sure extension_dir was set properly
moved libmysql.dll to the windows folder (or you could set it up in path but i just
want to get it running for now)
tested to see if php works, it does.
restarted server
tested php's mysql functions, none are recognized.
??
Which part did I do wrong?
