Put a space inside array in two-dimensional array

Question

I have two arrays:

$role = isset($_POST['role'])?$_POST['role']:'';
$details = isset($_POST['details'])?$_POST['details']:'';

Output for arrays is:

Role: Array ( [0] => leader [1] => follower ) 
Details: Array ( [0] => lead [1] => follow )

I want to assign leader to lead and follower to follow. Then I put two arrays into one:

foreach( $role as $rl => $r ) 
{
  $array_test3[] = array($r, $details[$rl]);
}

Output for print_r($array_test3) is:

Array ( [0] => Array ( [0] => leader [1] => lead ) [1] => Array ( [0] => follower [1] => follow ) )

Then I tried to implode an array:

$test3 = implode('<|>',array_map('implode',$array_test3));

Output for echo $test3.'<br/>'; is:

leaderlead<|>followerfollow

But I want is to get the following:

leader<|>lead<|>follower<|>follow

How can I do this?

You need to implode the inner array using the same parameter:

$test3 = implode('<|>',array_map(function ($innerArray) {
   return implode("<|>",$innerArray);
},$array_test3));

You could do something which was more a case of having a play and seeing how I could achieve this...

$role = ["leader","follower"];
$details = ["lead", "follow"];
$a1 = array_combine( $role, $details );
echo str_replace('=', '<|>', http_build_query($a1, '', '<|>'));
