In PHP, exec calls the command in an external EXE file, always fails, and asks the Master for guidance.
One of the Fossil.exe files, the file path has been added to the environment variable (or specify the exe file path)
In PHP, the
$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);

The first thing to be sure is that there is no problem with the $c command, because under the cmd command line, you can do it successfully!
But in the result of execution, $status is always 1 (0 indicates success)

But I put $c= "dir"; you can display all files or directories in the current directory
And the system method, and I tried, no.
Pcntl_exec () method is said to be non-UNIX system without this method, I faint dish ah!
Seek expert guidance Ah!
