ingres_fetch_array — Fetch a row of result into an array
Описание
$result
[, int $result_type
] )This function is an extended version of ingres_fetch_row(). 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.
If two or more columns of the result have the same field names, the last column will take precedence. To access the another column or columns of the same name, you must use the numeric index of the column or make an alias for the column. For example:
<?php
$result = ingres_query($link, "select ap_place as city, ap_ccode as country from airport where ap_iatacode = 'VLL'");
$result = ingres_fetch_array($result);
$foo = $result["city"];
$bar = $result["country"];
?>
With regard to speed, the function is identical to ingres_fetch_object(), and almost as quick as ingres_fetch_row() (the difference is insignificant).
By default, arrays created by ingres_fetch_array() start from position 1 and not 0 as with other DBMS extensions. The starting position can be adjusted to 0 using the configuration parameter ingres.array_index_start.
