I'm a php newbie.  I have an array that is the result of a ldap search.  I need to convert the multidimensional array into a file that can is imported by one of our applications.  The import part is automated and file has to delivered in that format.

The array is in the format that follows (I made values generic)

[recordnumber] => Array
        (
            [firstname] => Array
                (
                    [count] => 1
                    [0] => John
                )

            [0] => firstname
            [initials] => Array
                (
                    [count] => 1
                    [0] => R.
                )

            [1] => initials
            [lastname] => Array
                (
                    [count] => 1
                    [0] => smith
                )

            [2] => sn
            [mail] => Array
                (
                    [count] => 1
                    [0] => jsmith@domain.com
                )

            [3] => mail
            [count] => 4
            [dn] => uid=jsmith,dc=domain,dc=com
        )

Files needs to be in this format.  Last field is a value derived on the fly depending on whether person has certain access rights.

|Smith, John R.|jsmith@domain.com||

I found lots of code examples online. None of which I can make work.  I have to flatten the array which seems to be the most difficult part.

Thanks.
