如何使用PHP对象重用内存[关闭]

Question

I have a piece of code, which has to handle several hundred objects (images), but after the 77th instance it bumps into the 128 MB memory limit and dies.

The objects instaced by a static call which returns a new instance of the object:

foreach($imags as $imageId)
{
    $image = IMP::getById($imageId);
    ...
    ...
}

The problem is, that after each loop iteration the memory never gets freed, as seen below, each new imageobject eats up helluva lot of memory.

Memory usage:

...
20971520
22282240
23855104
25427968
27000832
28573696
30408704
32243712
34078720
35913728
38010880
39845888
...

Any ideas how can the object memory space be reused?
