Question

my MySQL query output is

dbcol_a | dbcol_b
dataA1 | dataB1
dataA1 | dataB2
dataA2 | dataB3
dataA2 | dataB4
dataA2 | dataB5

I wanna parse into struturized array like this:

arcol_a | arcol_b
dataA1 | dataB1
———-| dataB2
dataA2 | dataB3
———-| dataB4
———-| dataB5

thanks

Answer 1

This should do it:

$desired_array = array();
foreach ($query_output as $value)
{
  $desired_array[$value['arcol_a']][] = $value['arcol_b'];
}

This way you add each value in the second column to an array with an index of the first column.
