Question

我想基于值的数组创建一个具有组键的数组。

例如，我有这个数组：

array(17) { 
    ["user-insert-resp.php"]=> string(3) "123" 
    ["login.php"]=> string(3) "123" 
    ["project-list.php"]=> string(3) "123" 
    ["logout.php"]=> string(3) "123" 
    ["index.php"]=> string(3) "123" 
    ["project-view.php"]=> string(2) "13" 
    ["download.php"]=> string(2) "13" 
    ["sip-creator-resp.php"]=> string(2) "23" 
    ["project-remove-resp.php"]=> string(1) "2" 
    ["statistic.php"]=> string(2) "23" 
    ["graficoUsers.php"]=> string(2) "23" 
    ["statistic-topD.php"]=> string(2) "23" 
    ["statistic-topV.php"]=> string(2) "23" 
    ["user-edit-resp.php"]=> string(1) "3" 
    ["statistic-proj.php"]=> string(1) "3" 
    ["statistic-disc.php"]=> string(1) "3" 
    ["graficodisc.php"]=> string(1) "3" 
}

我想创建另一个这样的数组：

123 => ["user-insert-resp.php","login.php","project-list.php","logout.php","sip-creator-resp.php"]
13 => ["project-view.php","download.php"]
23 => ["sip-creator-resp.php","statistic.php","statistic-topD.php","statistic-topV.php"]
2 => ["project-remove-resp.php"];
3 => ["statistic-proj.php","statistic-disc.php","graficodisc.php"]

Answer 1

您可以在http://php.net/manual/en/function.array-flip.php轻松找到array_flip()。

Answer 2

这是你在找什么？

$data = array();
$data["user-insert-resp.php"] = "123";
$data["login.php"] = "123";
$data["project-view.php"] = "13";


$flipped_data = array();
foreach($data as $key=>$value){
    if(!isset($flipped_data[$value])){
        $flipped_data[$value] = array();
    }
    $flipped_data[$value][] = $key;
}

结果：

Array ( 
[123] => Array ( [0] => user-insert-resp.php [1] => login.php ) 
[13] => Array ( [0] => project-view.php )
)

基于值数组php的组密钥
