PHP - How to get array value using its key?

Question

How do I get the value of an associative array using its key. For example, I have:

$new = array(

array(
"post" => "anything",
"newt" => "Nothing"
),
array(
"post" => "something",
"newt" => "Filthy"
),
    array(
"post" => "one value",
"newt" => "normal"
),
    array(
"post" => "two value",
"newt" => "happy"
),
    array(
"post" => "Three",
"newt" => "more"
)
);

Now I want to get the value of post. That means I want to get echoed anything, something. How do I accomplish this? I tried a way but that's not working. Example;

print_r($new['post']);

I also tried echo $new['post']; but doesn't work. Please help

`echo $new[0]['post'];` (returns:anything) and `echo $new[1]['post'];` (returns:something) — , Apr 14 '14 at 22:21

@Dagon I mean by one line of code either `print` or `echo` instead of two echoes — user3293145, Apr 14 '14 at 22:23

`echo $new[0]['post'].' '.$new[1]['post'];` sorry this is really *basic syntax* stuff you should learn — , Apr 14 '14 at 22:24
@Dagon Sorry I have edited my question. Is there a way to get all values at once rather than doing `echo $new[0]['post']` and 1,2,3 and so on. I mean something like `print_r($new['post'])` and it would print `value1,value2,value3,value4` — user3293145, Apr 14 '14 at 22:30

after the edit i guess you want more than 2 ?

so ..

foreach ($new as $n){
echo $n['post'].',';
}

You can do like this

foreach($new as $key => $value){
  echo $value['post']."<br/>"; 
}

Incase you don't need the key:

foreach($new as $value){
  echo $value['post']."<br/>"; 
}
