卓越飞翔博客PHP如何对数据展开排序，这里须要使用PHP默认的ORDER BY方法。
ORDER BY使用方法
ORDER BY SELECT column_name(s) FROM table_name
ORDER BY预设对记录进行升序排序，如果你想降序排序，请使用 DESC 关键字。
ORDER BY SELECT column_name(s) FROM table_name DESC
实例代码
下面的实例选取 "Persons" 表中存储的所有数据，并根据 "Age" 列于对结果展开排序：
<?php
$con=mysqli_connect("localhost","username","password","database");
// 检测相连接
if (mysqli_connect_errno())
{
echo "连接失利: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM Persons ORDER BY age");
while($row = mysqli_fetch_array($result))
{
echo $row['FirstName'];
echo " " . $row['LastName'];
echo " " . $row['Age'];
echo "
";
}
mysqli_close($con);
?>
以上结果将输入：
