Question

首先我展示代码，帮助我，最后我将解释我需要什么。的数据库

CREATE TABLE IF NOT EXISTS `tickets` (
      `ticketid` int(10) NOT NULL AUTO_INCREMENT,
      `datetime` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
      `game` enum('1','2','3') NOT NULL DEFAULT '1',
      `gameid` int(100) NOT NULL,
      `userid` int(11) NOT NULL DEFAULT '0',
      `sum` int(11) NOT NULL,
      `username` varchar(50) NOT NULL,
      `numbers` varchar(27) NOT NULL,
      `count` int(2) NOT NULL,
      `how_much_win` int(20) NOT NULL,
      `win` enum('yes','no') NOT NULL DEFAULT 'no',
      `checked` enum('yes','no') NOT NULL DEFAULT 'no',

$arr = mysqli_query($GLOBALS["___mysqli_ston"], "SELECT numbers FROM tickets WHERE checked = 'no'") or sqlerr(__FILE__, __LINE__);
    if (mysqli_num_rows($arr) > 0){
        while ($res = mysqli_fetch_assoc($arr)) {
               foreach (explode("|", $res['numbers']) as $value) {
                        $numbers[$value]++;
               }    
       }

$numbers_f = array();
foreach($numbers as $num => $value){
    $numbers_f[$num] += $value;
}

foreach(range(1, 70) as $num){
  $numbers_f[$num] = (isset($numbers_f[$num]) ? $numbers_f[$num] : 0);
}

rsort($numbers_f,SORT_NUMERIC); 
$top=array_slice($numbers_f,0,10); //top 10
$butt=array_slice($numbers_f,(53));  //bottom 17
print_r($top);  
//echo implode(",", $top);
echo"<br />";
//echo implode(",", $butt);
print_r($butt);
}

此处的结果是 $ value ，如何通过 $ num 以查看 结果>，现在只按 $ value 排序。非常感谢你的帮助。

根据您的评论，我认为现在这是解决您问题的正确方法。

使用arsort()代替rsort()来保留键值对。

由于 PHP 5.0.2 array_slice()接受可选参数 preserve_keys ，应设置 TRUE 即可。否则PHP重新索引数组。

    $input =  '2|10|8|10|22|44|5|38|3|22|10'; //input values for testing
    $numbers = array();

    foreach (explode("|", $input) as $value) {
        $numbers[$value]++;
    }    

    $numbers_f = array();
    foreach(range(1, 70) as $num){
      $numbers_f[$num] = (array_key_exists($num, $numbers_f) ? $numbers_f[$num] : 0);
    }   


    foreach($numbers as $num => $value){
        $numbers_f[$num] += $value;
    }    

    arsort($numbers_f); //preserving key-value pairs

    $top=array_slice($numbers_f, 0, 10, true); //top 10
    $butt=array_slice($numbers_f, 53, null, true);  //bottom 17
    print_r($top);  
    //echo implode(",", $top);
    echo"<br />";
    //echo implode(",", $butt);
    print_r($butt);

在 PHP 5.0.2 之前，可以使用这样的函数代替 array_slice（）：

function slice( $array, $offset, $length = null ) {
    $keys = array_keys( $array ); // read the keys of the input array
    $values = array_values( $array ); // read the values of the input array

    $end = is_int( $length ) ? $length : ( sizeof( $array ) - $offset ); //length to slice

    $new = array();

    for ( $i = $offset; $i < $offset + $end; $i++ ) {
        $new[$keys[$i]] = $values[$i]; //fill new array with sliced content
    }

    return $new; //return sliced array
}

在php中改变数组排序代码
