pg_fetch_object

(PHP 3>= 3.0.1, PHP 4 )

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).

row is row (record) number to be retrieved. First row is 0.

Speed-wise, the function is identical to pg_fetch_array(), and almost as quick as pg_fetch_row() (the difference is insignificant).

Замечание: From 4.1.0, row is optional.

From 4.3.0, result_type is default to PGSQL_ASSOC while older versions' default was PGSQL_BOTH. There is no use for numeric property, since numeric property name is invalid in PHP.

result_type may be deleted in future versions.

Пример 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;

$qu = pg_query ($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;
    $row++;
}
echo "----------\n"; 
?>
</PRE> 
<?php
pg_free_result ($qu);
pg_close ($db_conn);
?>

Замечание: From 4.1.0, row became optional. Calling pg_fetch_object() will increment internal row counter counter by 1.
