# maxdb_fetch_array

(no version information, might be only in CVS)

maxdb_fetch_array -- Fetch a result row as an associative, a numeric array, or both

## Description

Procedural style:

mixed maxdb_fetch_array ( resource result [, int resulttype] )

Returns an array that corresponds to the fetched row or `NULL` if there are no more rows for the resultset represented by the result parameter.

maxdb_fetch_array() is an extended version of the maxdb_fetch_row() function. In addition to storing the data in the numeric indices of the result array, the maxdb_fetch_array() function can also store the data in associative indices, using the field names of the result set as keys.

> 注: 此函數傳回的欄位是有大小寫之分。

> 注: This function sets NULL fields to PHP `NULL` value.

If two or more columns of the result have the same field names, the last column will take precedence and overwrite the earlier data. In order to access multiple columns with the same name, the numerically indexed version of the row must be used.

The optional second argument resulttype is a constant indicating what type of array should be produced from the current row data. The possible values for this parameter are the constants MAXDB_ASSOC, MAXDB_NUM, or MAXDB_BOTH. By default the maxdb_fetch_array() function will assume MAXDB_BOTH for this parameter.

By using the MAXDB_ASSOC constant this function will behave identically to the maxdb_fetch_assoc(), while MAXDB_NUM will behave identically to the maxdb_fetch_row() function. The final option MAXDB_BOTH will create a single array with the attributes of both.

## Return values

Returns an array that corresponds to the fetched row or `NULL` if there are no more rows in resultset.

## Example

範例 1. Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, state FROM hotel.city ORDER by zip";
$result = maxdb_query($link, $query);
/* numeric array */
$row = maxdb_fetch_array($result, MAXDB_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = maxdb_fetch_array($result, MAXDB_ASSOC);
printf ("%s (%s)\n", $row["NAME"], $row["STATE"]);
/* associative and numeric array */
$row = maxdb_fetch_array($result, MAXDB_BOTH);
printf ("%s (%s)\n", $row[0], $row["STATE"]);
/* free result set */
maxdb_free_result($result);
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    New York (NY)
    New York (NY)
    Long Island (NY)
