Php数组usort函数

Question

我有一个简单的足球队阵列：

   Array
(
    [0] => Array
        (
            [name] => MANCHESTER
            [pts] => 8
            [gd] => 5
        )

    [1] => Array
        (
            [name] => BOURNEMOUTH
            [pts] => 3
            [gd] => 2
        )

    [2] => Array
        (
            [name] => STOKE CITY
            [pts] => 2
            [gd] => 4
        )

    [3] => Array
        (
            [name] => LIVERPOOL
            [pts] => 3
            [gd] => 5
        )
    [4] => Array
        (
            [name] => ARSENAL
            [pts] => 9
            [gd] => 1
        )

)

• 名称-是团队名称
• 得分-每个队的总分
• gd-是每支球队的进球差异

我想先按照pts对团队进行排序，然后如果我们有相同的pts，按gds排序。

我们只按pts进行排序：

function sortByOrder($a, $b){
    return $a['pts'] - $b['pts'];
}
usort($this_is_my_array, 'sortByOrder');

结果数组是：

ARSENAL (pts:9, gd:1)
MANCHESTER (pts:8, gd:5)
BOURNEMOUTH (pts:3, gd:2)
LIVERPOOL (pts:3, gd:5)
STOKE CITY (pts:2, gd:4)

但是对于BOURNEMOUTH & LIVERPOOL，我们需要重复pts，所以我们需要得到这样的结果：

ARSENAL (pts:9, gd:1)
MANCHESTER (pts:8, gd:5)
LIVERPOOL (pts:3, gd:5)
BOURNEMOUTH (pts:3, gd:2)
STOKE CITY (pts:2, gd:4)

Answer 1

试着

uasort($your_array, function($a,$b){
    $c = $b['pts'] - $a['pts'];
    $c .= $b['gd'] - $a['gd'];
    return $c;
});
print_r($your_array);

Fiddle

Answer 2

试试这个：

    $array=array(
    array("name"=>"MANCHESTER","pts"=>"8","gd"=>"5"),
    array("name"=>"BOURNEMOUTH","pts"=>"3","gd"=>"2"),
    array("name"=>"STOKE CITY","pts"=>"2","gd"=>"4"),
    array("name"=>"LIVERPOOL","pts"=>"3","gd"=>"5"),
    array("name"=>"ARSENAL","pts"=>"9","gd"=>"1")
    );
  foreach ($array as $key => $row) {
    $searchcountvalue[$key]  = $row['name'];
    $pastsearchcountvalue[$key] = $row['pts'];
    $abstract_count[$key] = $row['gd'];   
}array_multisort($pastsearchcountvalue, SORT_DESC, $abstract_count,  SORT_DESC, $array);
echo "<pre>";print_r($array);

Answer 3

使用这种格式的数组，请尝试检查此解决方案。

    $s[] = array
        (
            'name' => 'MANCHESTER',
            'pts' => 8,
            'gd' => 5
        );

$s[] = array
        (
            'name' => 'BOURNEMOUTH',
            'pts' => 3,
            'gd' => 2
        );      
$s[] = array
        (
            'name' => 'STOKE CITY',
            'pts' => 2,
            'gd' => 4
        );

   $s[] = array
        (
            'name' => 'testing',
            'pts' => 2,
            'gd' => 6
        );

$s[] = array
        (
            'name'=> 'LIVERPOOL',
            'pts' => 3,
            'gd' => 5
        );      

$s[] = array
        (
            'name' => 'ARSENAL',
            'pts' => 9,
            'gd' => 1
        );





 function array_orderby()
{
    $args = func_get_args();
    $data = array_shift($args);
    foreach ($args as $n => $field) {
        if (is_string($field)) {
            $tmp = array();
            foreach ($data as $key => $row)
                $tmp[$key] = $row[$field];
            $args[$n] = $tmp;
            }
    }
    $args[] = &$data;
    call_user_func_array('array_multisort', $args);
    return array_pop($args);
}




$sorted = array_orderby($s, 'pts', SORT_DESC, 'gd', SORT_DESC);

// OutPut

Array

    [0] => Array
        (
            [name] => ARSENAL
