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!!

that's a very common thing actually, to address an array items individually.

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).

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)];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");

How to echo key and value of an array without and with loop
$keys = array_keys($page);
implode(',',$keys);
echo $keys[0].' is at '.$page['Home'];
Comments
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;
}
}
foreach.
