Question

我有一个像这样的数组。

  [Badi Assad] => Array
    (
        [last_name] => Assad
        [first_name] => Badi
        [artist_name] => 
        [asterick] => *
        [slug] => badiassad
    )

[Ben Taylor] => Array
    (
        [last_name] => Taylor
        [first_name] => Ben
        [artist_name] => Ben Taylor
        [asterick] => *
        [slug] => bentaylor
    )

[Beverly] => Array
    (
        [last_name] => Hills
        [first_name] => Beverly
        [artist_name] => Beverly
        [asterick] => 
        [slug] => Eedih
    )

[Bruce Cockburn] => Array
    (
        [last_name] => Cockburn
        [first_name] => Bruce
        [artist_name] => Bruce Cockburn
        [asterick] => *
        [slug] => brucecockburn
    )

[Bohème] => Array
    (
        [last_name] => 
        [first_name] => Cassidy
        [artist_name] => Bohème
        [asterick] => *
        [slug] => cassidy
    )

我将如何进行排序，以便将姓氏和艺术家姓名按顺序排列，其中姓氏胜过艺术家名称，除非它是空的。

结果应该是这样的。

  [Badi Assad] => Array
    (
        [last_name] => Assad
        [first_name] => Badi
        [artist_name] => 
        [asterick] => *
        [slug] => badiassad
    )
[Bohème] => Array
    (
        [last_name] => 
        [first_name] => Cassidy
        [artist_name] => Bohème
        [asterick] => *
        [slug] => cassidy
    )
[Bruce Cockburn] => Array
    (
        [last_name] => Cockburn
        [first_name] => Bruce
        [artist_name] => Bruce Cockburn
        [asterick] => *
        [slug] => brucecockburn
    )

[Beverly] => Array
    (
        [last_name] => Hills
        [first_name] => Beverly
        [artist_name] => Beverly
        [asterick] => 
        [slug] => Eedih
    )
[Ben Taylor] => Array
    (
        [last_name] => Taylor
        [first_name] => Ben
        [artist_name] => Ben Taylor
        [asterick] => *
        [slug] => bentaylor
    )

我目前正在尝试这个。

    $newartists = array();
foreach($users as $k => $v)
 {
    $name = (strlen($v['artist_name']) > 0) ? $v['artist_name'] : $v['first_name'].' '.$v['last_name'];
    $newartists[$name]['last_name'] = $v['last_name'];
    $newartists[$name]['first_name'] = $v['first_name'];
    $newartists[$name]['artist_name'] = $v['artist_name'];
    $newartists[$name]['asterick'] = $ask;
    $newartists[$name]['slug'] = $v['slug'];
}                    
$sort = array();
foreach($newartists as $k=>$v) {
    $sort['artist_name'][$k] = $v['artist_name'];
    $sort['last_name'][$k] = $v['last_name'];
}

array_multisort( $sort['last_name'], SORT_ASC,$sort['artist_name'], SORT_ASC, $newartists);

谢谢！

使用uasort function有点像这样：

<?php
    $newartists = array(
        '3' => array(
            'last_name'   => 'c',
            'artist_name' => 'c'
        ),
        '1' => array(
            'artist_name' => 'a'
        ),
        '2' => array(
            'last_name'   => 'b',
            'artist_name' => 'd'
        ),
    );

    function cmp($a, $b)
    {
        $result = 0;

        // Sort preferably by last name
        if (!empty($a['last_name']) && !empty($b['last_name'])) {
            $result = strcmp($a["last_name"], $b["last_name"]);

        // Failover to artist name sort
        } else {
            $result = strcmp($a["artist_name"], $b["artist_name"]);
        }

        return $result;
    }

    usort($newartists, "cmp");

结果

Array
(
    [1] => Array
        (
            [artist_name] => a
        )

    [2] => Array
        (
            [last_name] => b
            [artist_name] => d
        )

    [3] => Array
        (
            [last_name] => c
            [artist_name] => c
        )
)

按2个键排序数组
