(PHP 4 >= 4.0.6, PHP 5, PHP 7)
Fetch a result row as an associative array, a numeric array, or both
array fbsql_fetch_array ( resource $result [, int $result_type ] )
fbsql_fetch_array() is a combination of fbsql_fetch_row() and fbsql_fetch_assoc().
An important thing to note is that using fbsql_fetch_array() is NOT significantly slower than using fbsql_fetch_row(), while it provides a significant added value.
