PHP抓屏函数实现屏幕快照代码分享

代码如下:

<?php

* 屏幕快照

$im = imagegrabscreen();

imagepng($im, "myscreenshot.png");

* 抓取一个窗口(IE为例)

$browser = new COM("InternetExplorer.Application");

$handle = $browser->HWND;

$browser->Visible = true;

$im = imagegrabwindow($handle);

$browser->Quit();

imagepng($im, "iesnap.png");

$im = imagegrabscreen();

// 抓取IE窗口及窗口内容(IE为例)

$browser = new COM("InternetExplorer.Application");

$handle = $browser->HWND;

$browser->Visible = true;

$browser->Navigate("http://www.jb51.net");

/* Still working? */

while ($browser->Busy) {

com_message_pump(4000);

}

$im = imagegrabwindow($handle, 0);

$browser->Quit();

imagepng($im, "iesnap.png");

//IE全屏模式

$browser = new COM("InternetExplorer.Application");

$handle = $browser->HWND;

$browser->Visible = true;

$browser->FullScreen = true;

$browser->Navigate("http://www.jb51.nett");

/* Is it completely loaded? (be aware of frames!)*/

while ($browser->Busy) {

com_message_pump(4000);

}

$im = imagegrabwindow($handle, 0);

$browser->Quit();

imagepng($im, "iesnap.png");

?>

需要说明几点

1.这二种方法只能工作在windows下面,

2. 黑屏解决办法--->>web 服务器(iis或apache)做为windows服务时，必须打开"允许与桌面交互"的选项.(点击服务属性->登录->勾选"允许与桌面 交互".(一定要记得重起apache或其他的服务器才会有用,我已经成功，无庸质疑)

3.需要gb库版本为2.0.34(php5.2.2默认自带)
