pg_fetch_object -- Fetch a row as an object
Description
object pg_fetch_object (resource result, int row [, int
result_type])
pg_fetch_object() returns an object with
properties that correspond to the fetched row. It returns FALSE
if there are no more rows or error.
pg_fetch_object() is similar to
pg_fetch_array(), with one difference - an
object is returned, instead of an array. Indirectly, that means
that you can only access the data by the field names, and not by
their offsets (numbers are illegal property names).
result_type is optional parameter controls
how return value is initilized.
result_type is a constant and can take the
following values: PGSQL_ASSOC, PGSQL_NUM, and PGSQL_BOTH.
pg_fetch_array() returns associative array
that has field name as key for PGSQL_ASSOC. field index as key
with PGSQL_NUM and both field name/index as key with
PGSQL_BOTH. Default is PGSQL_BOTH.
Note:
result_type was added in PHP 4.0.
Speed-wise, the function is identical to
pg_fetch_array(), and almost as quick as
pg_fetch_row() (the difference is
insignificant).
See also pg_exec(), pg_fetch_array(),
pg_fetch_row() and pg_result().
Example 1. Postgres fetch object <?php
$database = "verlag";
$db_conn = pg_connect ("host=localhost port=5432 dbname=$database");
if (!$db_conn): ?>
<H1>Failed connecting to postgres database <?php echo $database ?></H1> <?php
exit;
endif;
$qu = pg_exec ($db_conn, "SELECT * FROM verlag ORDER BY autor");
$row = 0; // postgres needs a row counter other dbs might not
while ($data = pg_fetch_object ($qu, $row)) {
echo $data->autor." (";
echo $data->jahr ."): ";
echo $data->titel."<BR>";
$row++;
}
?>
<PRE>
<?php
$fields[] = Array ("autor", "Author");
$fields[] = Array ("jahr", " Year");
$fields[] = Array ("titel", " Title");
$row= 0; // postgres needs a row counter other dbs might not
while ($data = pg_fetch_object ($qu, $row)) {
echo "----------\n";
reset ($fields);
while (list (,$item) = each ($fields)):
echo $item[1].": ".$data->$item[0]."\n";
endwhile;
$row++;
}
echo "----------\n";
?>
</PRE>
<?php
pg_freeresult ($qu);
pg_close ($db_conn);
