Question

我有一个以下数组，

$versions = array
(
    '0.9.md5' => '/var/www/md5_test/0.9.md5',
    '1.0.0.md5' => '/var/www/md5_test/1.0.0.md5',
    '1.0.1.md5' => '/var/www/md5_test/1.0.1.md5',
    '1.0.2.md5' => '/var/www/md5_test/1.0.2.md5',
    '1.0.3.md5' => '/var/www/md5_test/1.0.3.md5',
    '1.0.9.1.md5' => '/var/www/md5_test/1.0.9.1.md5',
    '1.0.9.10.1.md5' => '/var/www/md5_test/1.0.9.10.1.md5',
    '1.0.9.10.md5' => '/var/www/md5_test/1.0.9.10.md5',
    '1.1.3.md5' => '/var/www/md5_test/1.1.3.md5',
    '1.0.9.2.md5' => '/var/www/md5_test/1.0.9.2.md5',
    '1.0.9.3.md5' => '/var/www/md5_test/1.0.9.3.md5',
    '1.0.9.8.md5' => '/var/www/md5_test/1.0.9.8.md5',
    '1.0.9.9.1.md5' => '/var/www/md5_test/1.0.9.9.1.md5',
    '1.0.9.9.md5' => '/var/www/md5_test/1.0.9.9.md5',
    '1.0.9.md5' => '/var/www/md5_test/1.0.9.md5',
    '1.1.0.md5' => '/var/www/md5_test/1.1.0.md5',
    '1.1.1.md5' => '/var/www/md5_test/1.1.1.md5',
    '1.1.2.md5' => '/var/www/md5_test/1.1.2.md5',
);

在这个数组中，我想按键排序。我搜索了，

Ex：它的顺序应该是：1.0.9.md5, 1.0.9.1.md5,.. , 1.0.9.10.md5, 1.0.9.10.1.md5

我试过了

ksort($versions);

但我无法得到我想要的东西。

Answer 1

如果这些是版本号，您需要按版本排序，以便1.0.9.2.md5出现在1.0.9.10.1.md5之前，那么您需要基于语义版本控制的自定义排序：

uksort($versions, 'version_compare');

删除“.md5” - ＆gt; ksort（） - ＆gt;再次添加“.md5”。

foreach($versions as $key => $value) {

    $newKey         = str_replace(".md5", "", $key);
    $new[$newKey]   = $value;

}

ksort($new);

foreach($new as $key => $value) {

    $newKey         = $key . ".md5";
    $result[$newKey]= $value;

}

print_r($result);

<强>结果：

Array
(
    [0.9.md5] => /var/www/md5_test/0.9.md5
    [1.0.0.md5] => /var/www/md5_test/1.0.0.md5
    [1.0.1.md5] => /var/www/md5_test/1.0.1.md5
    [1.0.2.md5] => /var/www/md5_test/1.0.2.md5
    [1.0.3.md5] => /var/www/md5_test/1.0.3.md5
    [1.0.9.md5] => /var/www/md5_test/1.0.9.md5
    [1.0.9.1.md5] => /var/www/md5_test/1.0.9.1.md5
    [1.0.9.10.md5] => /var/www/md5_test/1.0.9.10.md5
    [1.0.9.10.1.md5] => /var/www/md5_test/1.0.9.10.1.md5
    [1.0.9.2.md5] => /var/www/md5_test/1.0.9.2.md5
    [1.0.9.3.md5] => /var/www/md5_test/1.0.9.3.md5
    [1.0.9.8.md5] => /var/www/md5_test/1.0.9.8.md5
    [1.0.9.9.md5] => /var/www/md5_test/1.0.9.9.md5
    [1.0.9.9.1.md5] => /var/www/md5_test/1.0.9.9.1.md5
    [1.1.0.md5] => /var/www/md5_test/1.1.0.md5
    [1.1.1.md5] => /var/www/md5_test/1.1.1.md5
    [1.1.2.md5] => /var/www/md5_test/1.1.2.md5
    [1.1.3.md5] => /var/www/md5_test/1.1.3.md5
)

数组按键排序。
