I am using php on Linux / Apache server. I have Three type of directories like as
|_ Writeale Directory |_ PHP Files |_ Image Files
Writeable Directory would used only by PHP to writing some txt, images... PHP Files excuted by server and return HTML codes Image Files Directories contains only images like as jpeg gif swf ....
Which permisions needed for each directory? What is default permission for directory (created by FTP or PHP)? My server Default value is 755. Is it secure?
Has permissions any effect on server performance?
