        Dear Group,

        I'm a beginner in PHP and would like to know how
        do I use 'fopen()' to write to files, because of some
        wierd reason I have to set some flag because of a permission
        problem in PHP that does not allow me to "by default" write
        files to my 'httpdocs' directory. I can read files but not
        write to them. This is kinda strange, but yeah.


        Any help would really be appreciated.
        Thanks for your time.



        -Jacques.
