Make Title Path for Detail Pages

I have some data arrays, and I want to process it into a special url path for name ortitle. The array data is like the following.

Example Array

array (
  0 => 
  array (
    'name' => 'Alryntop', 
    'gender' => 'Laki-Laki',
    'age' => '20',
    'city' => 'Jakarta', 
  ),
  1 => 
  array (
    'name' => 'Andre Tau Aja', 
    'gender' => 'Laki-Laki',
    'age' => '33',
    'city' => 'Jakarta', 
  ),
);

Function

So I only process it using the PHP as follows; Where my spaces change to - and words become lowercase.

Script:

function getArrWithPath(array $arr, $position = '')
{
  foreach ($arr as $key => $item) {
    if($position == ''){
      $target = $item;
    }else{
      $target = $item[$position];
    }
    $target = strtolower($target);
    $target = str_replace(' ', '-', $target);
    $target = preg_replace('/[^A-Za-z0-9\-]/', '', $target);
    $arr[$key][$position.'_path'] = $target;
  }
   return $arr;
}

Result:

array (
  0 => 
  array (
    'name' => 'Alryntop', 
    'gender' => 'Laki-Laki',
    'age' => '20',
    'city' => 'Jakarta', 
    'name_path' => 'alryntop', 
  ),
  1 => 
  array (
    'name' => 'Andre Tau Aja', 
    'gender' => 'Laki-Laki',
    'age' => '30',
    'city' => 'Jakarta', 
    'name_path' => 'andre-tau-aja', 
  ),
);

With this result I can process the more specific detail page leads to the data in choice. Or the reader has better suggestions, discussing bellow please!
