Feln, Richard, Jim,
Thank you for responding.

Hi,
Well, first array_walk_recursive returns a boolean so what you are doing in
you script is append a boolean (true or false) that will be converted to
string. So if array_walk_recursive will return true you will have the string
"1" in $karamohOutput['test'], and if array_walk_recursive will retu

What I don't understand is why it did not append to the string as it
walked through each key/value pair.
It seems like even though the variable inside the function called by

Hi,
How does the input array look like (the contents of the $karamohArray
