Match strings, allowing for escape characters.

Regular expression to match either a single or double quoted string, taking into account escape characters: /(["'])((?:(?!\1|\\).|\\.)*?)\1/

It's recommended that you remove escape characters from the resulting string (replace \\((?=\%s|\\).) with \1 substituting %s for the matched quote character):

preg_match('/(["\'])((?:(?!\\1|\\\\).|\\\\.)*?)\\1/', $string, $matches);
$extractedStringValue = preg_replace(sprintf('/\\\\((?=\\\\|\\%s).)/', $matches[1]), '\1', $matches[2]);
