[Klug-general] PSCP from Windows to Linux via PHP

[Karl Buckland]

Hi Nathan,

I believe that, in Windows, exec("your_program.exe") actually calls:
cmd /c your_program.exe

Additionally, depending on the version of PHP you're using, PHP may,
or may not, automatically add quotes. If you're using PHP 5.2 or
earlier, then you need to surround your command with double quotes
yourself, so something like:
exec("\"your_program.exe\"");
Which would give you:
cmd /c "your_program.exe"

On linux, it all works directly and without any issues.

Hopefully that helps.

Karl
