<para>

<function>fbsql_fetch_array</function> is a combination of

An important thing to note is that using
|
|
<function>fbsql_fetch_array</function> is NOT significantly
|
|
slower than using <function>fbsql_fetch_row</function>, while it
|
|
provides a significant added value.

A constant and can take the following values:
|
|
<constant>FBSQL_ASSOC</constant>, <constant>FBSQL_NUM</constant>, or
|
|
<constant>FBSQL_BOTH</constant>.
|
|
</para>
|
|
<para>
|
|
When using <constant>FBSQL_BOTH</constant>, in addition to storing the
|
|
data in the numeric indices of the result array, it also stores the
|
|
data in associative indices, using the field names as keys.

<para>
|
|
Returns an array that corresponds to the fetched row, or &false;
|
|
if there are no more rows.
|
|
</para>
|
|
<para>
|
|
If two or more columns of the result have the same field names,
|
|
the last column will take precedence. To access the other column(s)
|
|
of the same name, you must the numeric index of the column or
|
|
make an alias for the column.
