foreach($page as $key => $value) {
  echo "$key is at $value";
}

For 'without loop' version I'll just ask "why?"

    This is fine... just wanted to know if it possible to get a value individually by referring it to as 0 or 1 etc... I have just started with these stuffs. Thank You very much!! – esafwan Aug 04 '10 at 15:28

    that's a very common thing actually, to address an array items individually. – Your Common Sense Aug 04 '10 at 15:37
  • Oh, OK. I understood your question as 'how to echo all key-value elements from an array without using a loop' - which would be silly thing to do IMHO (unless using array_walk like KennyTM did). – Mchl Aug 04 '10 at 15:43

    If your array consist only of one key and one value, it would be convenient not to have to use the loop. If you don't know the key: `key($page).' is at '.$page[key($page)];` – Simon Jul 18 '18 at 11:38

Without a loop, just for the kicks of it...

You can either convert the array to a non-associative one, by doing:

$page = array_values($page);

And then acessing each element by it's zero-based index:

echo $page[0]; // 'index.html'
echo $page[1]; // 'services.html'

Or you can use a slightly more complicated version:

$value = array_slice($page, 0, 1);

echo key($value); // Home
echo current($value); // index.html

$value = array_slice($page, 1, 1);

echo key($value); // Service
echo current($value); // services.html

If you must not use a loop (why?), you could use array_walk,

function printer($v, $k) {
   echo "$k is at $v\n";
}

array_walk($page, "printer");

Echo key and value of an array without and with loop

$array = array(
            'kk6NFKK'=>'name',
            'nnbDDD'=>'claGg',
            'nnbDDD'=>'kaoOPOP',
            'nnbDDD'=>'JWIDE4',
            'nnbDDD'=>'lopO'
         );


print_r(each($array));

Output

    [1] => name
    [value] => name

    The `each()` function has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged. Source: [php.net](https://www.php.net/manual/en/function.each.php) – Genki Aug 30 '20 at 07:15

for the first question

$key = 'Home';
echo $key." is at ".$page[$key];

My version without a loop would be like this:

echo implode(
    "\n", 
    array_map(
         function ($k, $v) { 
             return "$k is at $v"; 
         }, 
         array_keys($page), 
         array_values($page)
    )
);

A recursive function for a change;) I use it to output the media information for videos etc elements of which can use nested array / attributes.

function custom_print_array($arr = array()) {
    $output = '';
    foreach($arr as $key => $val) {
        if(is_array($val)){
            $output .= '<li><strong>' . ucwords(str_replace('_',' ', $key)) . ':</strong><ul class="children">' . custom_print_array($val) . '</ul>' . '</li>';
        }
        else {
            $output .=  '<li><strong>' . ucwords(str_replace('_',' ', $key)) . ':</strong> ' . $val . '</li>';
        }
    }
    return $output;
}

You can try following code:

foreach ($arry as $key => $value) 
{
      echo $key;
      foreach ($value as  $val) 
      {
         echo $val; 
      }
}
