regex - Capture numbers and strings from comma separatated value file -

i have file contains strings begins , end double quotes. each string can contain comma. numbers not begin or end double quotes. each integer , string separated comma. possible have null value.

i make groups witch each string , number. trying capture each group 1 @ time.

i have created regex, works every case unless there comma in string:

/(?:"?([^"]*)"?,){2}/u 

if remove ungreedy operator, regex works every case except null values.

here example of log file:

196778,"df,fdfsdf","4.4","ds-sdads231-33","mmh",1,,,,,,,023,1,"20150,62519535ty"
