In PHP, exec always fails to call commands in the external EXE file.
One of the fossil.exe files has been added to the environment variable (or the path of the exe file)
In PHP
$ C = "fossil clone-A admin http: // admin: 92dd3f@192.168.2.22: 9090/cgi-bin/repo/95965728-994d-4d5d-9746-d84356f5b593". $ localRepositoryPath;
Exec ($ c, $ output, $ status );

First of all, the $ c command is correct, because it can be successfully executed under the cmd command line!
But in the execution result, $ status is always 1 (0 indicates success)

However, if I set $ c = "dir";, all files or directories in the current directory can be displayed.
You have tried the system method.
The pcntl_exec () method is not available in non-unix systems. I am confused!
Please give me some advice!

Browser access and terminal access are two permissions. The browser has common user permissions, and sudo (user operation permissions) is installed on the sub-host)
Then: exec ("sudo". $ c, $ output, $ status );
