actually I have last log field as dynamic company_concept_ss=Asia,India,Ceo|location_concept_ss=Asia,India|general_concept_ss=India,Ceo,pay
all these fields are dynamic i.e the name and count of the fields can vary
and I want output
"company_concept_ss" => [
[0] "Asia",
[1] "India",
[2] "ceo"
]
and so on
