Question

Array ( 
 [0] => Array ( 
 [0] => 21 
 [SLOTID] => 21
 ) 
 [1] => Array ( 
 [0] => 4 
 [SLOTID] => 4

• hjpotter92: Use implode

Answer 1

$str = $arr[0][0] . ',' . $arr[1][0];

• Paul: @AwladLiton What do you want to do when you have more values? Create more strings, or modify that one string to be longer, or is this good enough?

Answer 2

Here is the standard way to do this

implode(",",$arr)
