Thanks for the explanation though I did know some of this already. What I'm
not sure of is how and where to use this.
Below is a little example of a member function that creates a new text file.
How/where should I use umask() ?
Also does it have any effect if the file isn't properly closet by fclose() ?
Little function example (member function of class file_handler):
--------------------------------------
function create_file($file_name) {
if (!$this->fp = @fopen($file_name, wb)) {
$this->error_msg .= $this->error_create ." ". $file_name .".";
return false;
} else {
$this->file = $file_name;
return $this->fp;
}
}
