(PHP 5)
mysqli_result::fetch_object -- mysqli_fetch_object — Returns the current row of a result set as an object
Object oriented style (method):
Procedural style:
The mysqli_fetch_object() will return the current row result set as an object where the attributes of the object represent the names of the fields found within the result set.
Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().
The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.
An optional array of parameters to pass to the constructor for class_name objects.
Returns an object with string properties that corresponds to the fetched row or NULL if there are no more rows in resultset.
Note: 本函数返回的字段名是区分大小写的。
Note: 本函数对 PHP NULL 值设定 NULL 字段。

Example #1 Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = $mysqli->query($query)) {
/* fetch object array */
while ($obj = $result->fetch_object()) {
printf ("%s (%s)\n", $obj->Name, $obj->CountryCode);
}
/* free result set */
$result->close();
}
/* close connection */
$mysqli->close();
?>
Example #2 Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = mysqli_query($link, $query)) {
/* fetch associative array */
while ($obj = mysqli_fetch_object($result)) {
printf ("%s (%s)\n", $obj->Name, $obj->CountryCode);
}
/* free result set */
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
