Many time user ask me how to count duplicate value comma separated string in Laravel 5.

The array_count_values() function counts all the values of an array.

$colorstring = 'A,A,B,C,D,A,B';
$colordata = explode(',', $colorstring);
$vals = array_count_values($colordata);

Output

Array ( [A] => 3 [B] => 2 [C] => 1 [D] => 1 )
