Is `^/` a chracter type in PCRE?

Question

Is ^/ a chracter type in PCRE?

Have seen it get mentioned in character classes. e.g. [^/]*.

Cannot find anything in Documentation

Answer 1

The caret ^ at the beginning of a character class denotes negated character classes. So [^/]* means zero or more characters other than /, and [^0-9]+ matches any string of characters without any digits etc.
