Problems with string values that contain dollar sign followed by a number

[kuntur-studio]

Well, I was trying to store a hash of a password on a yaml file and the value retrieved by spyc had some missing characters.
Looking closely I found that the missings were $1, $10 and that kind of combinations, then making some tracing I get to the line 780 and found this:
$explode[$key] = preg_replace('/YAMLString/',$saved_strings[$stringi],$value, 1);
So preg_replace thinks that those are backreferences and tries to do some replacing...
I think, that the same will be happening on other places too.

To solve it look at:

preg_quote will not work for quoting the replacement string, it is intended to work with patterns.
So as written here:
https://www.sitepoint.com/community/t/how-to-escape-replacement-string-for-preg-replace/5769/12

I've escaped the replacement string using this:
$explode[$key] = preg_replace('/YAMLString/', strtr($saved_strings[$stringi], array('\\' => '\\\\', '$' => '\$')), $value, 1);

Tested and working!
