I cant get my regexpression to work in php. It works in javascript (vuejs):
(?<=.+: )(.*)
I have this string:
NL: abcdef
and i would like to get
abcdef
Can someone please tell me what i am doing wrong?

1A simple `(?<=: ).*` (or `(?<=: )(.*)` if the match needs to be in a capturing group like the original one) would work here, but we'd need more samples. – Jeto Oct 18 '18 at 23:23

Okay, but the problem is that i have alot of different strings, where one is `NL: ` and the other `EN: `, `US: `, etc – Ernst Reidinga Oct 18 '18 at 23:23

So? Sounds like lookbehind for a colon (and space) should work fine? If not, can you post more examples for which that wouldn't work? – CertainPerformance Oct 18 '18 at 23:24

thank you! That did the trick :D – Ernst Reidinga Oct 18 '18 at 23:25

There are many ways to solve this using PHP/PCRE, one is to skip the preceding string using \K
[^:]+: \K(.*)
If you can add an anchor to the beginning of the string, even better: ^[^:]+: \K(.*)

1BTW: You said you used `(?<=.+: )(.*)` in JavaScript. However, this only works in Chrome v62+ (i.e. browsers supporting ECMA2018) but not in other major browsers because the lookbehind is not available in many JS' Regex flavor. – wp78de Oct 18 '18 at 23:51
