if set to TRUE the array result be modified as follows: If the result set contains more than two columns, the value will be an array of the values from column 2 to n. If the result set contains only two columns, the returned value will be a scalar with the value of the second column (unless forced to an array with the $force_array parameter).
used only if the query returns exactly two columns. If TRUE, the values of the returned array will be one-element arrays instead of scalars.
if TRUE, the values of the returned array is wrapped in another array. If the same key value (in the first column) repeats itself, the values will be appended to this array instead of overwriting the existing values.
