mysqli_result::fetch_object -- mysqli_fetch_object — Fetch the next row of a result set as an object
Beschreibung
Objektorientierter Stil
$class = "stdClass", array $constructor_args = []): object|null|falseProzeduraler Stil
$result, string $class = "stdClass", array $constructor_args = []): object|null|false
Fetches one row of data from the result set and returns it as an object,
where each property represents the name of the result set's column.
Each subsequent call to this function will return the next row within the
result set, or null if there are no more rows.
If two or more columns of the result have the same name, the last column will take precedence and overwrite any previous data. To access multiple columns with the same name, mysqli_fetch_row() may be used to fetch the numerically indexed array, or aliases may be used in the SQL query select list to give columns different names.
Hinweis: This function sets the properties of the object before calling the object constructor.
Hinweis: Feldnamen, die von dieser Funktion zurückgegeben werden, unterscheiden sich in der Groß-/Kleinschreibung.
Hinweis: Diese Funktion setzt NULL-Felder auf den PHP Wert-
null.
