[zlobnygrif at gmail dot com]

From: zlobnygrif at gmail dot com
Operating system: debian/ubuntu
PHP version:  5.4.17
Package:  *General Issues
Bug Type: Bug
Bug description:Memory leak when initializing objects

Description:

If I set object property run-time it uses more memory than equal default
property value.

Test script:
---
printf(PHP %s %s\n\n, PHP_VERSION, PHP_OS);

class Order {
public $id = '123';
public $number = '1234';
public $date   = '12345';
}

$orders = [];

printf(Test1\nMem before: %.2f mb\n, memory_get_usage(true) / 1024 /
1024);
for ( $i = 0; ++$i  10; )
{
$order = new Order;
$orders[] = $order;
}
printf(Mem after: %.2f mb\n\n, memory_get_usage(true) / 1024 / 1024);

unset($orders, $i);
$orders = [];

printf(Test2\nMem before: %.2f mb\n, memory_get_usage(true) / 1024 /
1024);
for ( $i = 0; ++$i  10; )
{
$order = new Order;
$orders[] = $order;
}
printf(Mem after: %.2f mb\n\n, memory_get_usage(true) / 1024 / 1024);

unset($orders, $i);
$orders = [];

printf(Test3\nMem before: %.2f mb\n, memory_get_usage(true) / 1024 /
1024);
for ( $i = 0; ++$i  10; )
{
$order = new Order;

$order-id = '123';
$order-number = '12345';
$order-date   = '123456';

$orders[] = $order;
}
printf(Mem after: %.2f mb\n\n, memory_get_usage(true) / 1024 / 1024);

unset($orders, $i);

printf(Mem after: %.2f mb\n\n, memory_get_usage(true) / 1024 / 1024);

Expected result:

no memory leaks

Actual result:
--
PHP 5.4.17-1~dotdeb.0 Linux

Test1
Mem before: 0.25 mb
Mem after: 16.25 mb

Test2
Mem before: 4.75 mb
Mem after: 16.25 mb

Test3
Mem before: 5.00 mb
Mem after: 24.25 mb

Mem after: 5.25 mb
