Question

我有以下阵列:

Array
(
    [Places] => Array
        (
            [public] => 0
            [entities] => Array
                (
                    ...
                )
        )
    [Issues] => Array
        (
            [public] => 1
            [entities] => Array
                (
                    ...
                )
        )

    [Source] => Array
        (
            [public] => 0
            [entities] => Array
                (
                    ...
                )
        )
)

我愿通过公共钥匙对阵列进行分类。我知道,我可能不得不使用<代码>sort或usort,但我不知道如何执行。

任何想法都会受到极大感谢。

Answer 1

usort($array, function ($a, $b) { return $a["public"] - $b["public"]; });

我将尝试

usort(usort(array, function), function);

我可以应要求尝试一部样本代码,但已经掌握了这一资料。

Answer 3

采用阵列:

$test   =   array(
         Places  => array(
             public  => 0,
             entities  => array(

            )
        ),
         Issues  => array(
             public  => 1,
             entities  => array()
        ),
         Source  => array(
             public  => 0,
             entities  => array()
        )
    );

    echo  <pre> ;
    print_r($test);
    echo  </pre> ;

    array_multisort($test,SORT_ASC,$test);

    echo  <pre> ;
    print_r($test);
    echo  </pre> ;

Answer 4

采用<代码>array_multisort进行这项工作的一般办法是将你的分类价值放在自己的阵列中,然后将这两种阵列作为主要的分类阵列。

如下:

$test   =   array(
     Places  => array(
         public  => 0,
         entities  => array(

        )
    ),
     Issues  => array(
         public  => 1,
         entities  => array()
    ),
     Source  => array(
         public  => 0,
         entities  => array()
    )
);

echo  <pre> ;
print_r($test);
echo  </pre> ;

$sort = array();
foreach ($test as $k => $a) {
    $sort[$k] = $a[ public ];
}

// placing $sort first in array_multisort causes $test to be sorted in same order as the values in $sort
array_multisort($sort,SORT_ASC,$test);

echo  <pre> ;
print_r($test);
echo  </pre> ;

Answer 5

你可以利用我们的召回功能。

function cmp($a, $b) {
  return $a[ public ] == $b[ public ] ? 0 : $a[ public ] > $b[ public ] ? 1 : -1;
}

usort($array, "cmp");

Answer 6

为此:

$code = "return (-1*strnatcmp($a[ public ], $b[ public ]));";
uasort($array, create_function( $a,$b , $code));
