suPHP and suExec are two modules that allow PHP to run with the permissions
of the user, making it easy to write files to disk. However, suPHP (and I
believe suExec, but I can't remember for sure) does not like 777
permissions.

Check!

Can you try a simplified form that checks for success along the way? 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?
