LEARN ABOUT PHP
ifx_fetch_row
IFX_FETCH_ROW(3) 1 IFX_FETCH_ROW(3)ifx_fetch_row - Get row as an associative arraySYNOPSIS
array ifx_fetch_row (resource $result_id, [mixed $position])
DESCRIPTION
Fetches one row of data from the result associated with the specified result identifier.
Subsequent calls to ifx_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows.
PARAMETERS
o $result_id
-$result_id is a valid resultid returned by ifx_query(3) or ifx_prepare(3) (select type queries only!).
o $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(3) unless you have used ifx_textasvarchar(1) or ifx_byteasvar-
char(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)
<br />", $rowcount);
die ("Please restrict your query<br />
");
}
if (! ifx_do ($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("
<br />");
$row = ifx_fetch_row($rid, "NEXT");
}
ifx_free_result ($rid);
