Multidimensional Array PHP Implode

Question

In terms of my data structure, I have an array of communications, with each communications_id itself containing three pieces of information: id, score, and content.

Answer 1

this comment based on @jon solution , just add functional code block

but i have to use loop because array_map does not accept second parameter

function array_column_implode($data_array = array(),$key = 'id', $delimiter = ',')
{
  if (function_exists('array_column'))
  {
    return implode($delimiter, array_column($data_array, $key));
  }
  else
  {
    $new_data_array = array();
    foreach ($data_array as $value) {
      if (isset($value[$key]))
      {
        $new_data_array[] = $value[$key];
      }
    }
    return implode($delimiter, $new_data_array);
  }
}
