guys. i had install my php, mysql and apache n i did all the configuration with a tutorial provided by my lecturer.. even it is simple, my systems works n i think it's in good condition. but, i have read a book -php bible, by converse- the installation manual said that i need to copy some .dll files from my php directory to my system directory which is C:\Window. i need to put in the php4ts.dll into c:\WINDOW and copy the C:\PHP\Sapi\php4apache.dll into my apache modules directory. b4 that i had installed my php using the php installer n not from the Zip php binary which has all the dll file which is being recommended to copy. the php installer dun have those dll things except the php4ts.dll. so, is it necessary to put all these .dll file into the C:\window file? or it will works just fine without em?
