Linux to generate snapshots of PHP Web pages (screenshot) (XVFB and Wkhtmltoimage)

In the travel strategy, you need to take the introduction page to generate PDF and JPG images, PDF generated by the "Mpdf HTML generated PDF", and HTML generated JPG again jammed. It is intended to be a pure program generation, but in addition to invoking the remote APIs provided by other Web sites to generate JPG, otherwise the Pure program (GD library and built-in functions, or encapsulated classes) did not find the perfect solution.

Install the extended wkhtmltoimage build.

The installation steps are as follows:

1, server-side download installation wkhtmltoimage,32 and 64-bit difference, the mood of the sky installed is CentOS 5.8 32-bit. However, the Wkhtmltoimage 0.11 version was downloaded but the following error occurred.

MV Wkhtmltoimage-amd64/usr/bin/wkhtmltoimage
In this way, the installation is successful, you can test wkhtmltoimage http://www.111cn.net/screenshot.png

2, php execution wkhtmltoimage generate pictures

The code is as follows	Copy Code
Set_time_limit (0); Shell_exec ('/usr/local/bin/wkhtmltoimage http://www.111cn.net//usr/local/wwwroot/111cn.net/5eyi.jpg ');

If you use foreach batch generation, sleep (10) is recommended, pausing for a few seconds after each build.
