二维数组排序 sort

sort.php

<?php

//指定数组以$keys键值排序  
function array_sort($array,$keys,$type='asc'){  
    //$array为要排序的数组,$keys为要用来排序的键名,$type默认为升序排序  
    $keysvalue = $new_array = array();  
    foreach ($array as $k=>$v){  
        $keysvalue[$k] = $v[$keys];  
    }  
    if($type == 'asc'){  
        asort($keysvalue);  
    }else{  
        arsort($keysvalue);  
    }  
    reset($keysvalue);  
    foreach ($keysvalue as $k=>$v){  
        $new_array[$k] = $array[$k];  
    }  
    return $new_array;  
}  
$hot_cat = array_sort($hot_cat,'count','desc'); //此处对数组进行降序排列</span>
