Combine multiple arrays and covert to string

I have two fields

  • first_name
  • last_name

Both are arrays.

I would like to combine the arrays and covert to a human readable
string. How can I achieve this?

Here is where I’m at:

        $firstName = $this->state['first_name'];
        $lastName = $this->state['last_name'];

        $firstLastName = array_combine($firstName , $lastName);

/* $firstLastName outputs:
   array:2 [▼
     "John" => "Doe"
     "Jane" => "Doe"

        $string = implode(', ', $firstLastName);


// $string outputs:
//"Doe, Doe" 
//Only getting the last names

How can I get this to output John Doe, Jane Doe?

Method 1

Use array_map to combine arrays

    $firstName = $this->state['first_name'];
    $lastName = $this->state['last_name'];
    $firstLastName = array_map(function($f, $l) { return $f.' '.$l;}, $firstName, $lastName);

Method 2

well something like this:

$res = [];
for($firstLastName as $k => $v){
   $res[] = "{$k} {$v}";
$string = implode(', ', $res);

or without joining them before:

$firstLastName = array_map(
    function($name, $last){ 
         return "{$name} {$last}";
