苦苦于对这个数组进行排序:
它是数据库驱动的,它被添加如下:
$distanceArray[] = array($attractionID => $tempDistance);
,使用pre标签的输出如下:
Array
(
[0] => Array (
[4] => 114.4
)
[1] => Array (
[3] => 16.1
)
[2] => Array (
[2] => 15
)
[3] => Array (
[1] => 21.4
)
)
我试过这个没有运气:
function cmp($a, $b)
{
return $a['tempDistance'] - $b['tempDistance'];
}
usort($distanceArray, "cmp");

试试这个......
$test = array(
array(4=>"114.4"),
array(3=>"16.1"),
array(2=>"15"),
array(1=>"21.4"),
);
$value = array();
foreach ($test as $key => $row)
{
$value[$key] = array_values($row);
}
array_multisort($value, SORT_ASC,$test);
print_r($value);
答案:数组([0] =>数组([0] => 15)[1] =>数组([0] => 16.1)[2] =>数组([0] => 21.4)[3] =>数组([0] => 114.4))
答案 1 :(得分:0)
我使用了以下内容:
asort($distanceArray);
foreach ($distanceArray as $key => $tempDistance) {
echo "$key = $tempDistance\n";
}
打印:
2 = 15 3 = 16.1 1 = 21.4 4 = 114.4
感谢您抽出时间帮我解决这个问题!
