Re: Negative memory_get_usage() Values

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";
    }

} ?> Chris chris@dented-planet.net On Nov 26, 2006, at 12:34 PM, Richard Lynch wrote:

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');
