Hi all, i am new with PHP, and i would like to know if it is possible to use one file by two different functions at the same time. That is, one function will read information from the top of the file, while second function will add information on the bottom of the file. Second function is much faster in its job so ther is no problem that first function will come to the end of the file before second function finish its work. Is this possible, or i need to break the file into more files that will be approached by only one function at the time? Thanks in advance Urosh
