PHP sample code for implementing web page screenshots by executing the CutyCapt command

When taking screenshots of the website, CutyCapt, a tool of the server, is used. You can directly use commands on the server to capture and generate pictures of the specified URL. However, when using php to execute system commands, it was found that it could not be executed, but commands with help information such as CutyCapt ("/usr/local/cutycapt/CutyCapt/xvfb-run.sh --help") could be executed, but the call was executed# The script of ##System Variables failed.
