What about this:
$str = 'text\\dfnfg\\dhdsg\\\\';
echo preg_replace('/\\\{2,}/', '', $str);
I think what was catching you out was that you were escaping the \ once
for the regex, but then it needed it again because it was in a single
quoted string, meaning 3 slashes in total. Took me a little while to
figure that out as well!
The {2,} part just tells it to only remove the slashes where they occur
in runs of two or more.
