@semanalitics I believe the s:4 is the length of the string value.
For instance, in my database, I have this:
s:16:”Washer and dryer”
Note the values equal how many characters follows.
I found your thread trying to figure out how to update the values globally (to fix typos) without editing the values and resaving every page that used it. Figured I’d help you while continuing to look for my answer. 🙂
