How to parse an array into a variable?

Question

PHP

The table has a field with data like [17650,17776,17777]
How can I use php to get each value from [] without a comma into a variable?
So that later the cycle could display each value separately.

Answer 1

$string = '[17650,17776,17777]';

preg_match_all('/\d+/', $string, $matches);

var_dump($matches[0]);

Answer 2

$string = '[17650,17776,17777]';
$array = eval("return " . $string . ";");
var_dump($array[0]);

Answer 3

explode ?
