Question

If I want to add values to an array in a while loop I could do $arr[] = "some". But how can I do this if I have an associative array, for example:

while($result = $result->fetch_array(MYSQLI_ASSOC))
{
   $arr[]["some_key"] = "some";
   $arr[]["other_key"] = "some2";
}

But this will give me something like Array ( [0] => Array ( [some_key] => some) [1] => Array ( [other_key] => some2). So what is the right way to add values into an associative array inside a loop?

Answer 1

Create a temporary array for your keys, and then push that temporary array onto the main one:

$arr = [];
loop(condition) {
    $tmp = [];
    $tmp['some_key'] = 'some value';
    $tmp['other_key'] = 'other value';
    $arr[] = $tmp;
}
