In the past, we could only take screenshots of web pages in asp.net. Now I will introduce how to use a plug-in in Linux to take screenshots of web pages in PHP. I hope it will be helpful to everyone.

Server side

To realize the screenshot program, you must use the server-side program: http://code.google.com/p/wkhtmltopdf/

You can convert web pages into pdf or images. There are differences between 32-bit and 64-bit. Find a version that suits your server.

Installation

The installation process is very simple: unzip -> find a suitable path to put it down...

Execute

Command line call 1

代码如下	复制代码
/servers/app/qtwebkit/wkHtmlToImage bKjia.c0m www.bKjia.c0m.png

The default resolution is relatively high, the picture will be very large, and it will take a certain amount of time to generate the picture.

php

The code is as follows

代码如下	复制代码
exec('/servers/app/qtwebkit/wkHtmlToImage bKjia.c0m www.bKjia.c0m.png');

Copy code

代码如下

复制代码

ob_start();
//如果将输出的文件名设置为'-'，则直接返回文件数据流
passthru('/servers/app/qtwebkit/wkHtmlToImage --width 800 --height 600 -quality 85 weibo.com -');
$fileName = self::cachePath() . '/' . self::name();
$content = ob_get_clean();

//写入图片文件，备用
//file_put_contents($fileName, $content);

//直接输出为图片
header("Content-type: image/png");
echo $content;
?>

exec('/servers/app/qtwebkit/wkHtmlToImage bKjia.c0m www.bKjia.c0m.png');

Detailed usage

The code is as follows

代码如下	复制代码
yum install fonts-chinese

Copy code

ob_start();
//If the output file name is set to '-', the file data stream will be returned directly
passthru('/servers/app/qtwebkit/wkHtmlToImage --width 800 --height 600 -quality 85 weibo.com -');
$fileName = self::cachePath() . '/' . self::name();
$content = ob_get_clean();

//Write image file for backup
//file_put_contents($fileName, $content);

//Directly output as a picture
header("Content-type: image/png");
echo $content;
?>
