Problem with PHP escaping double quotes in HTML formats

Question

I have a simple PHP script that I use to process a SQLite database. This is nothing unusual or complicated. But I noticed, looking at the records in the database, that everything that I enter in the form field with double quotes appears in the processing of forms, as if I avoided quotes with a backslash. Therefore, when I entered an entry with the name:

British light utility vehicle 10HP Tilly

what is displayed in the database:

British light utility vehicle 10HP \ "Tilly \"

I don't know where they come from, and even worse, even using the following preg_replace doesn't seem to delete them:

$name = preg_replace('/\\"/', '"', $_REQUEST['kits_name']);

If I unload $name, it still carries unwanted characters \.
