PHP在多维数组中查找并返回邻居值

Question

I have a multidimensional array like so:

array (size=4)
  0 => 
    array (size=2)
      'term' => string 'news-article' (length=12)
      'count' => int 139
  1 => 
    array (size=2)
      'term' => string 'industry-resource' (length=17)
      'count' => int 37
  2 => 
    array (size=2)
      'term' => string 'editorial' (length=9)
      'count' => int 33
  3 => 
    array (size=2)
      'term' => string 'bulletin' (length=8)
      'count' => int 12

and I'm trying create a function that searches for a term and returns it's neighboring value, count.

My inclination was to use array_search(), however using this returns false, I'm guessin because it's only searching the first layer of the array (0,1,2,3).

I'm not so much looking for an exact answer but a nudge in the right direction. I'm guessing it will require looping through the array, but I do not know how to approach getting the neighboring count value once the term value is located. Any help is appreciated!

You can just loop through the array and access them directly.

$search_term = "news-article";
$count = 0;
foreach($array as $element) {
    if($element['term'] == $search_term) {
        $count = $element['count'];
        break;
    }
}
