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

foreach ($two_darray as $key => $row) {
   foreach ($row as $key2 => $val) {
      ...
   }
}

No need to worry about how many elements are in each array, as foreach() will take care of it for you. If you absolutely refuse to use foreach, then just count() each array as it comes up.

$rows = count($two_d_array);
for ($row = 0; $row < $rows; $row++) {
     $cols = count($two_darray[$row]);
     for($col = 0; $col < $cols; $col++ ) {
        ...
     }
}
