Convert decimal to hex using PHP -

How to convert the decimal value into hex using PHP?

December: 68-55- 230-06-04-89

I like hex value this way

Hex: 44-37-E0-06 should -04-59 but instead its display 44-37-E0-6-4-59 

  $ per echo $ test = dechex (68) .. "-" dechex (55) "-" dechex (230) "-" dechex (06) "-" dechex (04) "-" dechex (89) ........   
 This gives me the output:  44-37-E0-6-4-59  // without 06-04  
 output me Something like  44-37-E0-06-04-59    
 
 
 For  44-37-E0-06-04-59  just add  0 ,  
  sprintf ('% 02x -% 02X -% 02X-% 02X-% 02X-% 02X ', 68, 55, 230, 06, 04, 89);

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). 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'
