(PHP 4, PHP 5, PHP 7)
pg_fetch_object — Fetch a row as an object
Description
pg_fetch_object
( resource $result
[, int $row
[, int $result_type = PGSQL_ASSOC
]] ) : object
pg_fetch_object
( resource $result
[, int $row
[, string $class_name
[, array $params
]]] ) : object
pg_fetch_object() returns an object with properties that correspond to the fetched row's field names. It can optionally instantiate an object of a specific class, and pass parameters to that class's constructor.
Note:
This function sets NULL fields tothe PHP
NULLvalue.
Speed-wise, the function is identical to pg_fetch_array(), and almost as fast as pg_fetch_row() (the difference is insignificant).
Parameters
result- PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
row- Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or
NULL, the next row is fetched. result_type- Ignored and deprecated.
class_name- The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.
params- An optional array of parameters to pass to the constructor for
class_nameobjects.
Return Values
An object with one attribute for each field
name in the result. Database NULL
values are returned as NULL.
FALSE is returned if row exceeds the number
of rows in the set, there are no more rows, or on any other error.
Examples
Example #1 pg_fetch_object() example
<?php $database = "store";$db_conn = pg_connect("host=localhost port=5432 dbname=$database");if (!$db_conn) { echo "Failed connecting to postgres database $database\n"; exit;}$qu = pg_query($db_conn, "SELECT * FROM books ORDER BY author");while ($data = pg_fetch_object($qu)) { echo $data->author . " ("; echo $data->year . "): "; echo $data->title . "<br />";}pg_free_result($qu);pg_close($db_conn);?>
