如何为每个循环排序a的结果？

Question

I have a list of strings var_dump($key) :

string(6) "samuel"
string(4) "john"
string(4) "alan"
string(5) "frank"
string(3) "bob"

They are a result of a loop from a multidimensional array:

foreach ($array as $key => $item) { 
   if(is_array($item)){
      if (stripos($key, $keySearch) !== false){
      var_dump($key);
      }
   }
}

Is it possible to sort this list of strings?

I tried:

   foreach ($array as $key => $item) {  
       if(is_array($item)){
          if (stripos($key, $keySearch) !== false){
          asort($key);
          var_dump($key);
          }
       }
    }

and also

foreach ($array as $key => $item) {  
       if(is_array($item)){
          if (stripos($key, $keySearch) !== false){
              array_multisort($key);
              var_dump($key);
          }
       }
    }

My sort attemts are not working. The problem is I cannot sort the array because it is a complex multidimensional array. So I somehow only want to sort the results. But I am not sure how to do that.

The result I wish for var_dump($key) would be:

string(4) "alan"
string(3) "bob"
string(5) "frank"
string(4) "john"
string(6) "samuel"

PHP - Sort Functions For Arrays

sort() - sort arrays in ascending order
rsort() - sort arrays in descending order
asort() - sort associative arrays in ascending order, according to the value
ksort() - sort associative arrays in ascending order, according to the key
arsort() - sort associative arrays in descending order, according to the value
krsort() - sort associative arrays in descending order, according to the key
