In php, Number of rows and columns in a 2 D array?

Question

I have a two dimensional array with unknown number of elements.

$two_darray[row][column]; //there will be an unknown integer values instead of row and column

Answer 1

for a php indexed two-dimensional array:

$arName = array(
  array(10,11,12,13),
  array(20,21,22,23),
  array(30,31,32,33)
);

$col_size=count($arName[$index=0]);

for($row=0; $row";
}

Output:

10 11 12 13
20 21 22 23
30 31 32 33
