Comment (by SergeyBiryukov):

 Replying to [comment:4 donmhico]:
 > I have a question. Instead of using regex to check if a string is in
 'serialized-format', why not use PHP's native `unserialize()` to actually
 unserialize the input string and check for its output. From the PHP docs,
 `unserialize()` would return either serialized value or `FALSE` if the
 passed data is not unserializeable.

 We needed a function that can detect serialized data without doing an
 actual unserialize test on it. See [4382] and the discussion in #2591.
