The array is randomly evaluated. Solution Solutions

The array is randomly evaluated.

PHP Code

  $json = <<
  
   Album. ', Track: '. $row->truck. '
   
';}
  

There is an array in JSON format. Store albums and tracks.
How do I randomly take out 4 albums, remove one track from each record, and do not repeat the 4 songs? (Album for albums, truck for tracks.) ）

------Solution--------------------
I'm wrong, not array_rand. Duplicate items appear
But his original data had to be repeated and needed to be dealt with again.

PHP Code

$data = Json_decode ($json), foreach ($data as $v) $r [$v->truck] = $v; $data = $r; $ar = Array_rand ($data, 4); foreach ($ar as $K) {    echo ' record: '. $data [$k]->album. ', Track: '. $data [$k]->truck. '
