It's strange how #sprintf changed behaviour.
sprintf('%8b', 11);

Previously: "00001011"
Now: " 1011"

It doesn't seem to depend on #php versions. For now I go with "%08b"

@SenseException As sprintf for sure is a wrapper to the underlying C-function a change in that will change all php functions regardless of the PHP-version... Was there a change in the C-lib?
@heiglandreas I haven't looked into the C-lib yet, but I have older compiled PHP versions at home I can use for a test before I do that. C is a good hint. 👍
