win32std res_set（）在图像资源编辑时不起作用，但内容是正确的

Question

I have a code, which is gets the icon images info:

$icon_data = file_get_contents ($_ARG['icon']);

$icons = [];
$offset = 4;
$icon_count = unpack ('S', substr ($icon_data, $offset, 2));
$icon_count = $icon_count[1];
$offset += 2;

for ($i = 0; $i < $icon_count; ++$i) {

    $icon = [];

    $val = unpack ('C', substr ($icon_data, $offset, 1));
    $icon['width'] = $val[1];
    $offset += 1;

    $val = unpack ('C', substr ($icon_data, $offset, 1));
    $icon['height'] = $val[1];
    $offset += 1;

    $val = unpack ('C', substr ($icon_data, $offset, 1));
    $icon['colors'] = $val[1];
    $offset += 2;

    $val = unpack ('S', substr ($icon_data, $offset, 2));
    $icon['planes'] = $val[1];
    $offset += 2;

    $val = unpack ('S', substr ($icon_data, $offset, 2));
    $icon['bitcount'] = $val[1];
    $offset += 2;

    $val = unpack ('L', substr ($icon_data, $offset, 4));
    $icon['size'] = $val[1];
    $offset += 4;

    $val = unpack ('L', substr ($icon_data, $offset, 4));
    $icon['offset'] = $val[1];
    $offset += 4;

    $icon['data'] = substr ($icon_data, $icon['offset'], $icon['size']);

    $icons[] = $icon;

}

$icon_group  = pack ('S', 0);
$icon_group .= pack ('S', 1);
$icon_group .= pack ('S', $icon_count);

for ($i = 0; $i < $icon_count; ++$i) {

    $icon_group .= pack ('C', $icons[$i]['width']);
    $icon_group .= pack ('C', $icons[$i]['height']);
    $icon_group .= pack ('C', $icons[$i]['colors']);
    $icon_group .= pack ('C', 0); // RESERVED
    $icon_group .= pack ('S', $icons[$i]['planes']);
    $icon_group .= pack ('S', $icons[$i]['bitcount']);
    $icon_group .= pack ('L', $icons[$i]['size']);
    $icon_group .= pack ('S', ($i + 1));

}

It's working like a sharm. For example, it's output of $icons variable looks like

Array

)

if icon file have three images for example. I tried to use it for resource edit via win32std res_get () function, but it do nothing, but [data] section content seems to be correct (I've compared it manually)

Here's my code which made this:

res_set ($exe_file, 'RT_GROUP_ICON', 'MAINICON', $icon_group);

for ($i = 0; $i < $icon_count; ++$i)
res_set ($exe_file, 'RT_ICON', '#'.($i + 1), $icons[$i]['data']);

and I also put this content hardcoded, like

res_set ($exe_file, 'RT_ICON', '#1', substr ($image_data, 214, 1640));

but there's no result.

Any help with this problem solve is appreciated.

Thanks a lot!
