# 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).

> Note: 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.

See also pg_query(), pg_fetch_array(), pg_fetch_row() and pg_fetch_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;

    $qu = pg_query ($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);
    ?>

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