php中的数组排序代码变化不大


little change array sort code in php

首先我展示代码,以获得帮助,最后我将解释我需要什么。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',
      PRIMARY KEY (`ticketid`)
    ) ENGINE=MyISAM;
INSERT INTO `tickets` (`ticketid`, `datetime`, `game`, `gameid`, `userid`, `sum`, `username`, `numbers`, `count`, `how_much_win`, `win`, `checked`) VALUES
(1, '2014-10-22 16:33:18', '1', 6592, 40294, 20, 'sergey', '13|19|31|49|50|61|65', 0, 0, 'no', 'no'),

(3, '2014-10-22 16:33:22', '1', 6592, 40294, 20, 'sergey', '2|14|31|42|48|56|64', 0, 0, 'no', 'no'),
(4, '2014-10-22 16:33:23', '1', 6592, 40294, 20, 'sergey', '8|11|26|34|37|42|44', 0, 0, 'no', 'no'),
(5, '2014-10-22 16:33:24', '1', 6592, 40294, 20, 'sergey', '5|27|28|55|60|62|67', 0, 0, 'no', 'no'),
(6, '2014-10-22 16:33:27', '2', 6592, 40294, 160, 'sergey', '1|15|19|25|38|47|62|64', 0, 0, 'no', 'no'),
(7, '2014-10-22 16:33:28', '2', 6592, 40294, 160, 'sergey', '2|6|40|45|54|56|69|70', 0, 0, 'no', 'no'),
(8, '2014-10-22 16:33:30', '3', 6592, 40294, 720, 'sergey', '1|7|23|47|54|55|57|59|68', 0, 0, 'no', 'no'),

页面

$arr = mysqli_query($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);
}

这里的结果是按$value,如何更改代码以查看$num的结果,并且像现在一样只按>$value序。非常感谢你的帮助。

根据您的评论,我认为这是解决您问题的正确方法。

  • 使用arsort()而不是rsort()来保留键值对
  • 由于 PHP 5.0.2array_slice()接受可选参数preserve_keys,该参数应设置为TRUE。否则,PHP会重新索引数组。

        $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);
    

PHP 5.0.2之前,可以使用这样的函数来代替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
}
