$arr = array(
    0 => array(
        'name' => 'Obi-Wan Kenobi',
        'age' => '104',
    ),
    1 => array(
        'name' => 'R2-D2',
        'age' => 89
    ),
    2 => array(
        'name' => 'C-3PO',
        'age' => 80
    ),
    3 => array(
        'name' => 'Chewbacca',
        'age' => 124
    ),
);

    
$rows = count($arr);  

for ($i = 0; $i < $rows; $i++) {
     echo "row " . $i . ": " . $arr[$i]['name'] . " - " . $arr[$i]['age'] . "\n";
}
   




/*
run:

row 0: Obi-Wan Kenobi - 104
row 1: R2-D2 - 89
row 2: C-3PO - 80
row 3: Chewbacca - 124
