$wpdb->get_results not returning an array

Question

I haven't really messed with $wpdb before, but I'm stuck hard on one part. I'm trying to get the values returned in an associative array.

I've tried both of these

$datarow = $wpdb->get_results("SELECT class_name FROM wp_wcs2_class WHERE id=$classnumber");
$datarow = $wpdb->get_results("SELECT class_name FROM wp_wcs2_class WHERE id=$classnumber",ARRAY_A);

but print_r $datarow; just errors out with Parse error: syntax error, unexpected T_VARIABLE

Any idea what's going wrong? I know the data is there because this returns the correct value:

$nameresult = $wpdb->get_var($wpdb->prepare("SELECT class_name FROM wp_wcs2_class WHERE id=$classnumber",ARRAY_A));

Answer 1

It has nothing to do with $wpdb. It's PHP parse error.

print_r is a function, so you can't do print_r $datarow; You should use print_r( $datarow ); instead.
