Answer 1

You should take a look at the System program execution section of the manual : PHP provides several functions that can be used to launch external commands / programs, including :

• exec() -- which can store the output of the command in an array
• shell_exec() -- which returns, as a string, the output of the command
• system() -- which echoes the output of the command

要从 php（在 linux 中）创建 pdf，您必须使用包装器。

$cmd = '/usr/bin/xvfb-run --server-args="-screen 0, 1920x1080x24" /usr/bin/wkhtmltopdf http://google.com /tmp/google.pdf';

exec($cmd);
