如果两个P相同，我想按值P对数组进行排序，如果两个PD相同则按PD排序，然后按PF与PA相同排序。
我是如何实现这一目标的？
我在PHP中有多维数组
PHP：
$abc = array(
array('id' => 1,'name' => 'abc','overall' => array('MP' => '2','W'=> '2','L' => '0','D'=> '0','PF' => '2904','PA' => '1932','PD' => '972','P' => '6')),
array('id' => 1,'name' => 'abc','overall' => array('MP' => '2','W'=> '1','L' => '1','D'=> '0','PF' => '2320','PA' => '1974','PD' => '346','P' => '3')),
array('id' => 1,'name' => 'abc','overall' => array('MP' => '2','W'=> '1','L' => '1','D'=> '0','PF' => '1620','PA' => '1824','PD' => '-204','P' => '3')),
array('id' => 1,'name' => 'abc','overall' => array('MP' => '2','W'=> '0','L' => '2','D'=> '0','PF' => '2200','PA' => '2300','PD' => '-100','P' => '0'))
);
HTML：
Array
(
[0] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 0
[L] => 2
[D] => 0
[PF] => 2200
[PA] => 2300
[PD] => -100
[P] => 0
)
)
[1] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 1
[L] => 1
[D] => 0
[PF] => 2320
[PA] => 1974
[PD] => 346
[P] => 3
)
)
[2] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 1
[L] => 1
[D] => 0
[PF] => 1620
[PA] => 1824
[PD] => -204
[P] => 3
)
)
[3] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 2
[L] => 0
[D] => 0
[PF] => 2904
[PA] => 1932
[PD] => 972
[P] => 6
)
)
)
想要这样的。
Array
(
[0] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 2
[L] => 0
[D] => 0
[PF] => 2904
[PA] => 1932
[PD] => 972
[P] => 6
)
)
[1] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 1
[L] => 1
[D] => 0
[PF] => 2320
[PA] => 1974
[PD] => 346
[P] => 3
)
)
[2] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 1
[L] => 1
[D] => 0
[PF] => 1620
[PA] => 1824
[PD] => -204
[P] => 3
)
)
[3] => Array
(
[id] => 1
[name] => abc
[overall] => Array
(
[MP] => 2
[W] => 0
[L] => 2
[D] => 0
[PF] => 2200
[PA] => 2300
[PD] => -100
[P] => 0
)
)
)
我试过这样的事。
$memberArray1 = usort($memberArray, function($a, $b) {
return $b['overall']['P'] - $a['overall']['P'];
});
$memberArray1 = usort($memberArray, function($a, $b) {
return $b['overall']['PD'] - $a['overall']['PD'];
});
但问题是，当我按P排序然后它可以工作但是当我像PD那样排序时，它按PD排序而不是P。
答案 0 :(得分：0)
您可以将uasort与rsort一起用作
uasort($abc,function($a,$b){
$c = $a['P'] - $b['P'];
$c .= $a['PD'] - $b['PD'];
$c .= $a['PF'] - $b['PF'];
$c .= $a['PA'] - $b['PA'];
return $c;
});
array_reverse($abc);
print_r($abc);
