PHP一个简单的数组排序

Question

I got 3 arrays in PHP 1. Place name - $places 2. Days spent in each place - $days 3. Hours spent in each place - $hours

For eg

$places=array(15,12,10,2,78,32);
$days=array(1,0,5,4,3,8);
$hours=array(0,12,8,9,0,14);

For places I am keeping places id

My actual worry is I need to sort places array according to alphabetic order of place name ( which is from database )

like

$ids=implode(',',$places);
$res=mysql_query("select * from places where WHERE id IN ($ids) ORDER BY name ASC");



while($row=mysql_fetch_array($res)){



echo $row['name']. 'Days Spent ' . $days . 'Hours : '.$hours ; 

}

My doubt is simple , I have to show days & hours spent in each places in this MySQL result , ie after sorted/ order by MySQL query ..

Please help , Thank you for your time

In your loop:

$key = array_search($row['id'], $places);
echo $days[$key];
echo $hours[$key];
