I've installed php and Apache web server on my small home windows 7 platform. Now everything works fine. But I get some condition in after i operate a php page. So I wish to begin to see the php error logs. And So I attempted to edit the php.ini file. However when I save it, it always states this file can be used by another progam. The same is true not let me make changes into it. I ended the apache web server, still not unable to edit. Can anybody let me know if anybody else faced this kind of problem? Do you know the programs that utilizes the php.ini file? Which services, programs or processes I must pause and make changes to php.ini file?
