Now, here is a pattern which actually means "a quote which doesn't
already have a backslash before it" which is achieved by means of a
lookbehind assertion, which, even when searching the string after the
first match, "'str", still 'looks back' on the earlier part of the
string to recognise the se

Did no one see why the regex was wrong?
I saw what the regex was. I didn't think like you that it was 'wrong'.
Once you unescape the characters in the PHP single-quoted string above
(where two backslashes count as one, and backslash-quote counts as a
quote)

How about an example that doesn't require escaping ALL the interesting
