试编写代码如下:
<?php
$array[] = array('id'=>1,'price'=>50);
$array[] = array('id'=>2,'price'=>70);
$array[] = array('id'=>3,'price'=>30);
$array[] = array('id'=>4,'price'=>20);
foreach ($array as $key=>$value){
$id[$key] = $value['id'];
$price[$key] = $value['price'];
}
array_multisort($price,SORT_NUMERIC,SORT_DESC,$id,SORT_STRING,SORT_ASC,$array);
echo '<pre>';
print_r($array);
echo '</pre>';
?>
运行结果:
Array
(
[0] => Array
(
[id] => 2
[price] => 70
)
[1] => Array
(
[id] => 1
[price] => 50
)
[2] => Array
(
[id] => 3
[price] => 30
)
[3] => Array
(
[id] => 4
[price] => 20
)
