I have the following string:
22/04/2020 14:10 by example@example.com
And I wrote the following regex:
^(\d{2,4}\/?)+
Why does group 1 only match the last part of the date and not the whole date, and how can I fix this?

1You are repeating the capturing group, capturing the value of the last iteration. Why not match the format? `^\d{2}/\d{2}/\d{4}` – The fourth bird Apr 22 '20 at 14:40

Yes, that is also an option, but I was wondering it also could be fixed the way I'm doing it. – Drago Apr 22 '20 at 14:41

Ok I think I solved it by doing `^((?:\d{2,4}\/?)+)` – Drago Apr 22 '20 at 14:49

You can make it a non capturing group instead `^(?:\d{2,4}\/?)+` and it could possibly also match a `/` at the end – The fourth bird Apr 22 '20 at 14:49

Note that regex store all matches in the array - firstly check in your code all matches. I think that the data that you need - already matched - you just need to store it. Following the Regex101 - Full match - will be your arr[0]. If you are using PHP - check this regex-tester = https://www.phpliveregex.com/
My regex :
^(\d+\W)*

How does this solve my problem? This would match all numbers and A-Za-z0-9_ – Drago Apr 22 '20 at 14:58
