1. Currently, the html2image third-party plug-in is installed on the centos 5.0 system.
Shell_exec in php cannot be called, but images can be generated through commands on the server.
For example, the html2image control is installed in the/home/www/web1 Directory. the php file is web2.php content.
Shell_exec ('./html2image forum.csdn.net csdn.jpg ');
?>
Failed to run web2.php.

However, you can directly run cd/home/www/web1 on the server./html2image forum.csdn.net csdn.jpg to generate images.

I don't know why.

2. do you have any good methods to generate images (webpages) on webpages?
