PHP - Deleting an entry from a multidimensional array

Question

I have an array like this:

$_SESSION['food'] = array( 

// ARRAY 1
array(
      "name" => "apple",
      "shape" => "round",
      "color" => "red"
  ),

// ARRAY 2
   array(
      "name" => "banana",
      "shape" => "long",
      "color" => "yellow"
  )
);

I want to search through all keys in all child arrays and delete the entire child array if the search term is found.

So, basically:

1. If searching for "long", the entire Array 2 is removed.
2. If searching for "apple", the entire Array 1 is removed.

How would I accomplish this?

Thanks!

Answer 1

This should do the trick:

foreach ($array as $key => $value) {
    foreach ($value as $child_value) {
        if ($child_value == $search_term) {
            unset($array[$key]);
            continue 2;
        }
    }
}
