mysqli_result::fetch_object -- mysqli_fetch_object — Fetch the next row of a result set as an object
Description
Object-oriented style
$class = "stdClass", array $constructor_args = []): object|null|falseProcedural style
$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.
Note: This function sets the properties of the object before calling the object constructor.
Note: Field names returned by this function are case-sensitive.
Note: This function sets NULL fields to the PHP
nullvalue.
Parameters
-
result -
Procedural style only: A mysqli_result object returned by mysqli_query(), mysqli_store_result(), mysqli_use_result() or mysqli_stmt_get_result().
-
class -
The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.
-
constructor_args -
An optional array of parameters to pass to the constructor for
classobjects.
Return Values
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, or false on failure.

Examples
Example #1 mysqli_result::fetch_object() example
Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = $mysqli->query($query);
/* fetch object array */
while ($obj = $result->fetch_object()) {
printf("%s (%s)\n", $obj->Name, $obj->CountryCode);
}
Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = mysqli_query($link, $query);
/* fetch associative array */
while ($obj = mysqli_fetch_object($result)) {
printf("%s (%s)\n", $obj->Name, $obj->CountryCode);
}
The above examples will output something similar to:
Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)
