Answer 1

You can use foreach to loop and iterate over each array and print it

$array1 = array('ICRAF Subjects','Agriculture/Agroforestry','ICRAF Subjects','Natural Resource Management','Science Domains','SD4-Land health decisions','Uncategorized',
    );

    $array2 = array(
    'ICRAF Subjects',
    'Agriculture/Agroforestry',
    'ICRAF Subjects',
    'Natural Resource Management',
    'Science Domains',
    'SD4-Land health decisions',
    'Sustainable development Goals SDG',
    'SDG13-Climate change',
    );

    $array3 = array
    (
    'Uncategorized',
    );

    $array4 = Array
    (
    'ICRAF Subjects',
    'Agriculture/Agroforestry',
    );

    $newarr = [$array1, $array2, $array3, $array4];

    foreach($newarr as $arr){
    echo '<br>';
      echo '(';
      echo '<br>';
      foreach($arr as $ar){
        echo $ar;
        echo '<br>';
      }

      echo ')';
    echo '<br>';
    }
