保持数组$array键值由大到小排序

下面一起来了解下保持数组$array键值由大到小排序，相信大家看完肯定会受益匪浅，文字在精不在多，希望保持数组$array键值由大到小排序这篇短内容是你想要的。

需求：要求保持数组$array键值由大到小，并且其中相同键值的键名要从小到大排序

实现代码如下：

';$array = array(    '5' => 100,    '3' => 80,    '1' => 80,    '4' => 60,    '0' => 60,    '2' => 40);$kArr=array();$vArr=array();$newkArr=array();foreach($array as $key=>$value){        $kArr[]=$key;        $vArr[]=$value;}$kStr=implode(",",$kArr);$repeatArr=array();foreach($array as $k=>$v){        $arrn[$v][]=$k;}foreach($arrn as $k=>$v){        if(count($v)>1){                //echo $k.'重复下标为';                $aa='';                foreach($v as $vv){                        $aa .= $vv.',';                }                $bb=substr($aa, 0, -1);                $bbarr=explode(',',$bb);                sort($bbarr);                $bbstr=implode(',',$bbarr);                $repeatArr[$bb] = $bbstr;        }}foreach($repeatArr as $key=>$value){        $kStr=str_replace($key,$value,$kStr);}$newkArr=explode(',',$kStr);echo '
';$c=array_combine($newkArr,$vArr);print_r($c);

今天有个高手帮写了个方法：一起膜拜下

function sysSortArray($ArrayData,$KeyName1,$SortOrder1 = "SORT_ASC",$SortType1 = "SORT_REGULAR"){        if(!is_array($ArrayData)){                return $ArrayData;        }        // Get args number.        $ArgCount = func_num_args();        // Get keys to sort by and put them to SortRule array.        for($I = 1;$I < $ArgCount;$I ++){                $Arg = func_get_arg($I);                if(!eregi("SORT",$Arg)){                        $KeyNameList[] = $Arg;                        $SortRule[]    = '$'.$Arg;                }                else{                        $SortRule[]    = $Arg;                }        }        // Get the values according to the keys and put them to array.        foreach($ArrayData AS $Key => $Info){                foreach($KeyNameList AS $KeyName){                        ${$KeyName}[$Key] = $Info[$KeyName];                }        }        // Create the eval string and eval it.        $EvalString = 'array_multisort('.join(",",$SortRule).',$ArrayData);';        eval ($EvalString);        return $ArrayData;}$data = array('0'=>60,'1'=>80,'2'=>40,'3'=>80,'4'=>60,'5'=>100);$sorts=array();foreach($data as $k => $val){        $sorts[$k]['k']=$k;        $sorts[$k]['val']=$val;}$rs=sysSortArray($sorts,'val',"SORT_DESC","k","SORT_DESC");print_r($rs);die;
