mysqli_result::fetch_row -- mysqli_fetch_row — Fetch the next row of a result set as an enumerated array
面向对象风格
过程化风格
Fetches one row of data from the result set and returns it as an enumerated
array, where each column is stored in an array offset starting from 0 (zero).
Each subsequent call to this function will return the next row within the
result set, or null if there are no more rows.
注意: 此函数将 NULL 字段设置为 PHP
null值。
result
仅以过程化样式：由 mysqli_query()、mysqli_store_result()、 mysqli_use_result()、mysqli_stmt_get_result() 返回的 mysqli_result 对象。
Returns an enumerated array representing the fetched row, null if there
are no more rows in the result set, 或者在失败时返回 false.

<?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 ($row = $result->fetch_row()) {
printf("%s (%s)\n", $row[0], $row[1]);
}
过程化风格
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = mysqli_query($mysqli, $query);
/* fetch associative array */
while ($row = mysqli_fetch_row($result)) {
printf("%s (%s)\n", $row[0], $row[1]);
}
以上例程的输出类似于：
Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)
