Memory Leak ?

[K]

Hi,

I am using PHP 4.3.9 in Linux 2.4.20-37. When I run this program:

echo "Memory Usage: " . memory_get_usage() . "\n";
for($i=1;$i<1000;$i++){
$dom = domxml_open_file("xml/ht_players.xml");
unset($dom);
}
echo "Memory Usage: " . memory_get_usage() . "\n";

I get the this results:

Memory Usage: 15336
Memory Usage: 795544

Why memory usage grow so much if I use unset($dom)?. There is anyway
to prevent/fix this ?

Grettings.

PS: excuse my bad english :S

Hi,

I had the same problem today and after some searching I found something
interesting. (but didn't tested it yet)

you should use $dom->free() instead of unset($dom)

it's not documented but it exists since 4.3.3
