php - php将字符串转换为数组以进行组？

问题描述

我有字符串组我想按组和子组爆炸

例如

operation.user.add
operation.user.edit
operation.permission.add
performance.tool.add
performance.tool.remove
operation.permission.edit
operation.tool.delete
operation.tool.remove

想要的结果如下：

Array
(
['operation'] => Array
    (
        ['user'] => Array
            (
                [0] => 'add',
                [1] => 'edit'
            ),
        ['permission'] => Array
            (
                [0] => 'add',
                [1] => 'edit'
            ),
        ['tool'] => Array
            (
                [0] => 'delete',
                [1] => 'remove'
            ),
    ),
['performance'] => Array
    (
        ['tool'] => Array
            (
                [0] => 'add',
                [1] => 'remove'
            )
    )
)

任何人都可以提供解决方案我如何将字符串转换为上述数组？

解决方案

假设这是一个字符串值，这可能是你能得到的最有效的：

$str = 'operation.user.add
operation.user.edit
operation.permission.add
performance.tool.add
performance.tool.remove
operation.permission.edit
operation.tool.delete
operation.tool.remove';
$output = [];
foreach (explode("\n", $str) as $string) {
    $parts = explode('.', $string);
    $output[$parts[0]][$parts[1]][] = $parts[2];
}
print_r($output);

输出：

Array
(
    [operation] => Array
        (
            [user] => Array
                (
                    [0] => add
                    [1] => edit
                )    
            [permission] => Array
                (
                    [0] => add
                    [1] => edit
                )    
            [tool] => Array
                (
                    [0] => delete
                    [1] => remove
                )    
        )    
    [performance] => Array
        (
            [tool] => Array
                (
                    [0] => add
                    [1] => remove
                )    
        )    
)
