ifx_fetch_row -- Get row as enumerated array
Description
array
ifx_fetch_row ( int result_id [, mixed position] )
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. Returns FALSE on error
result_id is a valid resultid returned by
ifx_query() or
ifx_prepare() (select type queries only!).
position is 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.
ifx_fetch_row() fetches one row of data from
the result associated with the specified result identifier. The
row is returned as an array. Each result column is stored in an
array offset, starting at offset 0, with the column name as key.
Subsequent calls to ifx_fetch_row() would
return the next row in the result set, or FALSE if there are no
more rows.
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);
?>
