note 35617 added to function.fopen

I understand the difference between "r" and "r+": Without the "+" after the "r", a following "fwrite()" is ignored. But can someone really explain precisely the difference between : $file=fopen("file.htm","a") and $file=fopen("file.htm","a+") ...without repeating allways the same stuff ("a"=Open for writing only; ..."a+"=Open for reading and writing;...) In both cases, one can read and write !!! So where is the difference ? The same question concerns "w" and "w+". Thank you for any concise help.
