使用路径描述符访问和修改数组或JSON文档。

用法和示例

假设您有一个这个数组，它可能更大，您不知道某些路径是否存在

<?php

use Denno\PathFinder\PathFinder;

$array = [
    'some' => [
        'multi' => [
            'dimensional' => [
                'array' => 'foo',
            ],
        ],
    ],
];

检查给定路径是否存在

echo PathFinder::getPathValue($array, 'some.multi.dimensional.array');
echo PathFinder::getPathValue($array, 'some.multi.nonexisting.key');

会返回

true
false

如果您想修改给定路径的值，您可以这样做

echo PathFinder::setPathValue($array, 'some.multi.dimensional.array', 'bar');
//would return 'bar'
//let's check it:
echo PathFinder::getPathValue($array, 'some.multi.dimensional.array');
//would return true.

//but a nonexisting path? 
echo PathFinder::setPathValue($array, 'some.multi.nonexisting.key', 'foobar');
//would return false, because the path don't exist!

//but you want it to be created and the value set? No problem:
echo PathFinder::setPathValue($array, 'some.multi.nonexisting.key', 'foobar', true);
//the last parameter, named 'force', will create it for you if set to true and therefor return 'foobar'
