|
<function>ingres_fetch_array</function> Returns an array that
|
|
corresponds to the fetched row, or &false; if there are no more
|
|
rows.

|
This function is an extended version of
|
|
<function>ingres_fetch_row</function>. 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>
|
|
<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 use the numeric index of the
|
|
column or make an alias for the column.

Speed-wise, the function is identical to
|
|
<function>ingres_fetch_object</function>, and almost as quick as
|
|
<function>ingres_fetch_row</function> (the difference is
|
|
insignificant).
