How can I print all the values of an array? [closed]

Question

I have an array and print_r won't display the raw text, how can I print all the values in an array (e.g. pie)

Answer 1

So many ways to do it...

foreach ($array as $item) {
    echo $item;
}

echo join(', ', $array);

array_walk($array, create_function('$a', 'echo $a;'));

Answer 2

<?php
$len=count($pie);
for ($i=0;$i<$len;$i++)
   echo $pie[$i];
?>
