PHP - 如何使用其键获取数组值？

Question

如何使用其键获取关联数组的值。例如，我有：

$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"
)
);

现在我希望得到post的值。这意味着我希望得到回应anything, something。我该如何做到这一点？我尝试了一种方法但是没有用。实施例;

print_r($new['post']);

我也试过了echo $new['post'];但是没有用。请帮忙

Answer 1

编辑后我猜你想要超过2个？

所以..

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

Answer 2

你可以这样做

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

如果您不需要密钥：

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

PHP＆gt; = 5.5.0

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