Basic principle of setting up the permission of hosting files & folderRecently while working in a web application i faced some unpredictable problems. After googling i realized that the problem is the permission label of files & directories. Now a days we are very much used to work with cpanel to manage our hosting files & credentials As we working in graphical mode (not in command mode), we used to ignore about file attributes. File attributes are the collection of file information (for example: what the owner can do with the file, what people in the group can do, and what others can do, various time stamps etc). While managing hosting files, file attributes is very important. Because if any file is given write permission to world, your application / site may destroy or remove any time. On the other hand lowest label of file permission may prevent your targeted visitor to read.
