Yes, and thats one my the problems. Like in this dump:
$VAR1 = [

           [
             '12345',
             'MONICA',
             '01/01/1900',
             '0X10'
           ],
           [
             '000001',
             'MARY L',
             '01/01/2000',
             '0111P'
           ],
           [
             '8884',
             'JOHN M.',
             '01/01/1932',
             '0OK8'
           ],
    ];

$VAR1 = [

           [
             'Main',
             '1900',
             'Red',
           ],
           [
             'APT',
             '1290',
             'Blue',
           ],
           [
             'AVAL',
             '1921',
             'Green',
           ],
    ];


$VAR1 = [

          [
            'Q3.0',
            'OK',
            '1900-01-01',
            'N',
            'O',
            'O',
            'X',
            'Y'
          ],
          [
            '12w',
            'PL',
            '2000-01-02',
            'N',
            'P',
            'O',
            'X',
            'A'
          ],
    ];

The code would fail, because in the first array $princ, it contains 3 arrays or:
$VAR1 = [

           [
             '12345',
             'MONICA',
             '01/01/1900',
             '0X10'
           ],
           [
             '000001',
             'MARY L',
             '01/01/2000',
             '0111P'
           ],
           [
             '8884',
             'JOHN M.',
             '01/01/1932',
             '0OK8'
           ],
    ];

So, if any of the others don't match the size of $princ I would get this error:
Can't use an undefined value as an ARRAY reference at...

That is becuase of $person only having 2 arrays:
$VAR1 = [

          [
            'Q3.0',
            'OK',
            '1900-01-01',
            'N',
            'O',
            'O',
            'X',
            'Y'
          ],
          [
            '12w',
            'PL',
            '2000-01-02',
            'N',
            'P',
            'O',
            'X',
            'A'
          ],
    ];

I was thinking if there is a way to check the first array for its number of elements and make sure that all the others would match its size, that way the code would have the right data structure. What do you think?
