How to clone a git repository from php over ssh?

Question

PHP

OS: Windows
Downloaded https://git-scm.com/download/win so that you can work with Git via cmd.
My project creates a folder and I need to clone the repository into it via PHP. I do it with code like this:

$query = 'git clone ssh://[email protected]*************.git G://**********************';
$tmp = exec($query);

PS The first asterisks are the path to the repository, the second - to the folder
When I run the $query command simply through cmd, cloning occurs without problems. And if you run it through PHP, the folder is deleted. What is the reason? How to fix?
