How can the exec() function in PHP be used to start an external program, such as an AutoIt script?

To start an external program, such as an AutoIt script, using the exec() function in PHP, you can provide the path to the AutoIt executable and the path to the script as arguments to exec(). Make sure that the AutoIt executable is installed on the system and that the script file exists in the specified path.

// Path to AutoIt executable
$autoitPath = "C:/Program Files/AutoIt3/AutoIt3.exe";

// Path to AutoIt script
$scriptPath = "C:/path/to/autoit_script.au3";

// Command to execute AutoIt script
$command = "$autoitPath $scriptPath";

// Start the external program (AutoIt script)
exec($command);
