推荐答案

虽然您可以使用 ，您将只能在Windows框上使用它，即使那样也很棘手.

While you might be able to do something with imagegrabscreen or imagegrabwindow you'd only be able to use it on a Windows box, and even then it would be tricky.

您必须打开浏览器窗口以找到指定的url(您可以使用exec进行此操作)，并使用上述方法抓取屏幕截图.

You'd have to open a browser window to the specified url (you could do that with exec) and grab a screenshot using the aforementioned methods.

以下是 imagegrabwindow 的手册条目中的示例:

Here's an example from the manual entry for imagegrabwindow:

<?php
$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$browser->Navigate("http://www.libgd.org");

/* Still working? */
while ($browser->Busy) {
    com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");
imagedestroy($im);
?>
