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) — user557846

@Dagon I mean by one line of code either print or echo instead of two echoes — user3293145

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/>"; 
}

PHP >= 5.5.0

foreach(array_column($new, 'post') as $post) {
  echo $post;
}
