Bug description: Memory leak in SimpleXML ?
Description:
------------
I'm processing big XML file (1-10MB each) in loop.
Very soon free memory is near to zero and system starts swapping.
Reproduce code:
---------------
<?
function ProcessFile($filename)
{
if (file_exists($filename)) {
$xml =
simplexml_load_string(file_get_contents($filename));
foreach ($xml->report as $reports)
{
//echo $reports->forumid."\n";
}
// var_dump($xml);
unset($xml);
} else {
exit('Failed to open test.xml.');
}
}
$files=file('files.txt');
foreach ($files as $file)
{
$file=chop($file);
echo "Processing $file\n";
ProcessFile($file);
}
?>
