How about something like the code below to see how far it gets (I haven't tested, but it should be close): <?php // let's make sure you see the E_WARNING errors if present for file functions error_reporting(-1); // set var for later $cost = 120.89; if (!($fp = fopen("test.txt", 'w'))) { echo "Can't open or create file!"; } else if (!($len = fprintf($fp, "In the year 3000, a Coke will cost %01.2f, with tax.", $cost))) { echo "Can't write to file!"; } else if (!(fclose($fp))) { echo "Can't properly close file!"; } ?> What do you see if you run this?
