How to find the number of rows in an array?

Question

PHP

array(
    'a'=>'b'
    'b'=>'c'
    'c'=>'d'
    'd'=>'e'
    'e'=>'f'
    'f'=>'g'
    );

Answer 1

$arr = array(
    'a'=>'b'
    'b'=>'c'
    'c'=>'d'
    'd'=>'e'
    'e'=>'f'
    'f'=>'g'
    );

echo count($arr);

if you need the number of exactly string values, then:

function count_strings($array) {
  $count = 0;
  foreach ($array as $item) {
    if (is_string($item))
      $count++;
  }
  
  return $count;
}
