Is the “continue X” syntax unique for PHP, or was it also in C and/or other languages? [closed]

Today, I finally learned that it’s possible to do “continue 2;” to “continue” an inner loop. I never knew about this syntax in 20+ years of using PHP. I could have used this in so many cases…

Now I wonder:

1. Was this a thing right away, or added “late in the game” for PHP?
2. Did this also exist in C/other languages, or was it an enhancement in PHP?

I tried to find this out on my own prior to asking.
