change the path of input in exec() PHP

Question

I want that the path from which the file is uploaded C:\\xampp\\htdocs\\cmd is coming from dirname(__FILE__), but when i do that the script throws an error.

Working code

exec( dirname(__FILE__)."\\xyz.exe C:\\xampp\\htdocs\\cmd\\blue.png D:\\1.png\", $output);

But I want:

exec( dirname(__FILE__)."\\xyz.exe" dirname(__FILE__)."\\blue.png D:\\1.png\", $output);

Answer 1

Why not chdir before executing all:

$imagename = 'blue.png';
$command = 'chdir ' . __DIR__ . '; xyz.exe ' . $imagename . ' D:\\1.png\\ ';
exec( $command, $output);
