What is the data format of teamNames in formula attributes (in php code)?

[cpicanco]

Hi people,

I was reading this instruction (https://www.espocrm.com/documentatio...on-in-formula/) on how to create your own "contain" function and I am wondering what is the data format of the casesNames or teamsNames there in php code. Is it a plain text in json format? Is it a json object? Something else?

I am trying to write a custom function that will return true if a piece of text is found in one of the names inside casesNames and false otherwise.

Probable a array of strings.
