Backtracking Verb Information

Question

I was looking for information about these verbs, There is little information about this, I only found such information on Wikipedia , but not about the verbs that they just talked about. I googled it, but not so lucky, I just found examples from here (stack overflow), applying it. But did not succeed.

I want to know if they are available for PCRE, because I use PHP, and I saw one example about it, but I do not know about it. I want to know if information exists, a list of o verbs, etc. thanks

Examples (* ANY) (* FAIL)

Answer 1

You can look here and here .

Two constructs that directly change the back trace are the Atomic group and the Posessive (super greedy) quantifier .

PS Sorry if I misunderstood the question
