Okay, I modified the script as follows to allow for collecting data
and graphed it. The graph is at http://dented-planet.net/graph.png
(sorry, I'm not versed in created perfect charts).
<?php
$x = '';
for ($i = 1; $i <= 20000; $i++) {
$x = utf8_encode('this is a test');
if ($i % 100 === 0) {
echo $i . ' ' . memory_get_usage() . ' ' . memory_get_usage
(true) . "\n";
}
}
?>

What version of PHP and what OS?
I *think* that there is some jiggery-pokery going on in
memory_get_usage() in PHP 5 and managed memory where it would make
perfect sense to get negative numbers occasionally...
You may also want to log the memory_get_usage inside the loop, and
then graph the memory usage as it goes up/down to get a better idea of
what's going on.

Hey gang,
I'm getting a negative return value from memory_get_usage() using the
following script. My I've got --enable-memory-limit enabled and my
memory_limit is set to 100MB (which should more than enough memory).
I suspect that there is a bug in utf8_encode() but I'd like others to
test it (on different platforms) before I submit it as a bug.
<?php
for ($i=0; $i < 20000; $i++) {
echo utf8_encode('This is a test');
}
echo memory_get_usage();
