Question

mysql_fetch_array will give me an array of a fetched row. What\'s the best way generate an array from the values of all rows in one column?

Answer 1

$query = mysql_query('SELECT * from yourTable');
function mysql_field_array( $query ) {
    $field = mysql_num_fields( $query );
    for ( $i = 0; $i < $field; $i++ ) {
        $names[] = mysql_field_name( $query, $i );
    }
    return $names;
}

$fields = mysql_field_array( $query );
$output = implode( ',', $fields );   //outputs the columns names
//echo count( $fields );  //this use if you want count of columns.
$columns = '{\"fields\":\".json_encode($output).\"}';
echo $columns; //for JSON output
