Question

I want to return values I retrieve from the db using group_concat as an array of data. Is it possible to do this in the mysql query? Or do I need to explode the data into an array?

GROUP_CONCAT(sh.hold_id) as holds

returns this

[holds] => 3,4

I want it to return:

[holds] => array(3,4)

Answer 1

As I said in my comment: you need to explode the data into an array, using php code like this:

$holds = explode(',', $holds);

because mysql has no concept of array-type for data.
