# ifx_fetch_row

(PHP 3 >= 3.0.3, PHP 4, PHP 5)

ifx_fetch_row -- Get row as an associative array

## 说明

array ifx_fetch_row ( resource result_id [, mixed position] )

Fetches one row of data from the result associated with the specified result identifier.

Subsequent calls to ifx_fetch_row() would return the next row in the result set, or `FALSE` if there are no more rows.

## 参数

`result_id`

  `result_id` is a valid resultid returned by ifx_query() or ifx_prepare() (select type queries only!).

`position`

  An optional parameter for a "fetch" operation on "scroll" cursors: `NEXT`, `PREVIOUS`, `CURRENT`, `FIRST`, `LAST` or a number. If you specify a number, an "absolute" row fetch is executed. This parameter is optional, and only valid for SCROLL cursors.

## 返回值

Returns an associative array that corresponds to the fetched row, or `FALSE` if there are no more rows.

Blob columns are returned as integer blob id values for use in ifx_get_blob() unless you have used ifx_textasvarchar(1) or ifx_byteasvarchar(1), in which case blobs are returned as string values.

## 范例

例 1. Informix fetch rows

`<?php
$rid = ifx_prepare ("select * from emp where name like " . $name,
$connid, IFX_SCROLL);
if (! $rid) {
/* ... error ... */
}
$rowcount = ifx_affected_rows($rid);
if ($rowcount > 1000) {
printf ("Too many rows in result set (%d)\n<br />", $rowcount);
die ("Please restrict your query<br />\n");
}
if (! ifx_do ($rid)) {
/* ... error ... */
}
$row = ifx_fetch_row ($rid, "NEXT");
while (is_array($row)) {
for (reset($row); $fieldname=key($row); next($row)) {
$fieldvalue = $row[$fieldname];
printf ("%s = %s,", $fieldname, $fieldvalue);
}
printf("\n<br />");
$row = ifx_fetch_row($rid, "NEXT");
}
ifx_free_result ($rid);
?>`
