I am having a problem where a routine (that I cannot modify) is returning me either a 3 nested array -or- a 2 nested array. The key values are never the same, however, I’d like to normalize the nesting so that I can make the 2 nested array 3 levels deep every time to avoid “Notice: Undefined index:” errors. Or if possible, have a routine to count the number of levels deep the array is so I can code accordingly.
You can use isset() to determine if a particular level is present in the array. If not, add it.
