使用phprets从rets feed下载图像

我想用PHPRETS下载RETS FEED数据和图像，我成功下载了CSV数据，但是，虽然图像是在图像文件夹中正确创建的，但每个图像的大小是零。我附上我在这里使用的代码，请帮助我，以便我可以正确下载图像。使用phprets从rets feed下载图像

    // designates when a record was last modified

    // these might be something like RE_1, RES, RESI, 1, etc. 
    $property_classes = array("B");

    // using a really old date so we can get everything

你有这条线。它返回的是图像URL，而不是二进制图像数据。

$photos = $rets->GetObject("Property", "Photo", $record[$fo], "*", 1);

第五个参数应该是0。

$photos = $rets->GetObject("Property", "Photo", $record[$fo], "*", 0);

按照PHRETS文档中，1分返回图像URL和0返回二值图像数据。

Thanks..it为我工作！ – user38427

此外，图片网址将不会被所有RETS支持。因此，如果您出于某种原因需要URL，请确保公共URL支持由RETS提供。 –
