echo clear multidimensional array PHP

Question

it seems a simple question but I cannot remember why:

so... I have an array on $_POST and I want to make a echo of that variable:

Im doing this:

   function h()
   {
    foreach($_POST as $k => $v ){
   echo $v;

    }

Thats fine but I have a problem:

The $POST should be expecting two or more values, for example:

     Array ( [s-armenia] => TRIBUNAL ADMINISTRATIVO DE SUCRE [s-armenia2] => 0 ) 

so.. with my function I get this:

   TRIBUNAL ADMINISTRATIVO DE SUCRE 
   0

¿How echo my function without the 0?

Thanks in advance for your help.

Answer 1

Thanks guys for your help, I think about something simple like this and it works:

  function h()
 {
 foreach($_POST as $k)
  {
  $p = "/0/";
  $s = "";
  echo preg_replace($p, $s, $k);

  }

  }

Answer 2

foreach($_POST as $k)
{
   echo $k;
}

=> $v would be the key (which is 0)
your array should look like array(1 => 2, 3 => array(3.1 => 3.2), 4 => 5)

edit: adding from PHP manual:

<?php
$array = array(
    "foo" => "bar",
    42    => 24,
    "multi" => array(
         "dimensional" => array(
             "array" => "foo"
         )
    )
);

var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>
