can somone explain me the ^/ meaning in this pattern ([^/]+)? Is the ^ an negation flag for / and what would be the result if the ^ stand behind the / like /^?
My second question is why match these pattern on several strings without any flag like . <- point etc.?
Thanks in advance!
([^/]+)? Optional capturing group with a negated character class matches any character but not of / forward slash one or more times.
If ^ present at the start of a character class, then it would do negation. If it's at the middle or at the end like [/^], then it would acts like a normal character class which matches literal / or ^ symbols.
