我想使用php对下面的数组进行排序。该数组应按服务[0] [1]的值排序。
Array
(
[Services] => Array
(
[0] => Travel & Hotels ~72
[1] => Automotive~119
[3] => Professional Services~71
[4] => Home Services~70
[6] => IT Services & Computer Repair~83
[8] => Health and Medical~69
)
[Restaurants] => Array
(
[0] => American / Eclectic~2
[1] => Cafe~11
[2] => Desserts & Bakery~111
)
[Shopping] => Array
(
[0] => Office Equipment~103
[3] => Department Stores~91
[15] => Cosmetics & Beauty Supply~90
[16] => Musical Instruments & Teachers~102
[17] => Food~87
)
[Entertainment] => Array
(
[0] => Bars/Pubs~48
)
[Travel] => Array
(
[0] => Hotels~129
)
)
这样做应该很简单（假设$attractionArray是上面给出的外部数组）：
foreach($attractionsArray as $key => $innerArray)
{
sort($innerArray, SORT_STRING);
$attractionArray[$key] = $innerArray;
}
