Procedural style:
Object oriented style (method):
mysqli_result {
mixed fetch_object();
}
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. If no more rows exist in the current result set, NULL
is returned.
Returns an object that corresponds to the fetched row or NULL
if there are no more rows in resultset.
本函数返回的字段名是区分大小写的。
本函数对
PHP NULL
值设定 NULL 字段。
mysqli_fetch_array(), mysqli_fetch_assoc(), mysqli_fetch_row(), mysqli_query() 和 mysqli_data_seek().
<?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();
?>
<?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);
?>
