ifx_fetch_row

(PHP 4, PHP 5 < 5.2.1)

ifx_fetch_row — Get row as an associative array

Description

ifx_fetch_row ( resource $result_id [, mixed $position ] ) : array

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.

Parameters

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.

Return Values

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.

Examples

Example #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);
?>

If you use a select statement that

identifies fields according to which

table they come from, i.e.



select tab1.name, tab2.phone from

tab1, tab2

where tab1.id = tab2.id



then the associative keys of the array returned by ifx_fetch_row will not include the table names.  For the example above, if you used



$row = ifx_fetch_row ($rid);



then the first field in the

returned array would be $row["name"],

not $row["tab1.name"] .
