mysqli_result::fetch_object
(PHP 5, PHP 7, PHP 8)
Fetch the next row of a result set as an object
Description
Oop
Procedural
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.
Field-case Fetch-null
Parameters

Errors/Exceptions
A ValueError is thrown when the constructor_args is non-empty with the class not having a constructor.
