``object``null``false```mysqli_fetch_object` `mysqli_result` `result` `string` `class`"stdClass" `array` `constructor_args`[]

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.

This function sets the properties of the object before calling the object constructor.

`class`

&reftitle.returnvalues;

Returns an object representing the fetched row, where each property represents the name of the result set's column, &null; if there are no more rows in the result set, &return.falseforfailure;.
