php - preg_split() help, properly formatted regular expression -

-

I am very weak in regular expressions

I want to split these letters on:

  • Location ""
  • The hyphen "
  • Underscore" _ " < P> I have it: 
      preg_split ('/ \ + | - | \ | | _ /', $ string],   
     .. I suspect this is not correct - I like some advice on the "+" sign.   
     
     
     < Code> preg_split ('/ [+ \ s _-] /', $ string);  should work for you Unlike the squares, the characters are creating a character square.  
      Note  - It is sometimes important that  -  , So I keep it always kept safe.

Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

    github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

    -
    I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
