It's been said that this is just how the function works,
but it seems as though destroying allocations for an
anonymous function when redefining to the same variable
would be the way to handle it. Example:
for ($i=0; $i<10; $i++) {
$echoit = create_function('$wha', 'echo $wha;');
echo memory_get_usage();
$echoit(" on iteration: #$i\n");
}
How else can you dynamically modify function or code
without reloading a script?

This isn't a bug but how it works. Each create_function() call creates
a new unique function. So obviously if you define zillions in an
infinite loop you'll run out of memory.

the following code causes PHP to continually eat more and more memory
where it should be destroying the old reference for $func.
while(1) {
$array = array();
$func = create_function('', "return 0;");
$array[] = $func;
$func = 0;
echo "sleeping for a second.\n";
sleep(1);
}
