php - 具有多种变体的 Foreach 字符串替换

Question

我正在尝试找出使用多个排序规则替换字符串的最佳方法。

我有一个由用户插入的句子，我有一个数组，其中包含该句子中所有拼写错误的单词及其可能的更正。

$sentence = '我想从出租车上取回我的车辆';

我想显示以下内容:

1. 我想从出租车里取回我的车
2. 我想从出租车里取回我的车
3. 我想从出租车上换车

到目前为止的代码:

$element = array(
    "vehical" => array('vehicle'),
    "recovary" => array('recovery', 'recover', 'revary')
);

$sentence = 'i want to recovary my vehical from the cabs';

foreach($element as $i => $val){
    echo $i;    
}

编辑:扩展了另一个场景:

如果顶部数组中有多个变体，会发生什么情况。

    "vehical" => array('vehicle', 'vehiclesy', 'whatever'),
    "recovary" => array('recovery', 'recover', 'revary')

1. 我想从出租车里取回我的车
2. 我想从出租车上恢复我的车辆
3. 我想从出租车上拿回我的东西
4. 我想从出租车里取回我的车
5. 我想从出租车上恢复我的车辆
6. 我想从出租车上拿回我的东西
7. 我想从出租车上换车
8. 我想从出租车上换车
9. 我想从出租车上取回我的任何东西

您需要创建所有唯一的替换数据组合。对于这些组合中的每一个，您都可以进行替换。这是一种方法:

<?php
function createCombinations(array $input)
{
    $head = array_shift($input);
    $tail = count($input) > 1 ? createCombinations($input) : array_shift($input);

    $combinations = [];
    foreach ($head as $left) {
        foreach ($tail as $right) {
            $combinations[] = array_merge([$left], (array) $right);
        }
    }

    return $combinations;
}

$element = [
    'vehical'  => ['vehicle', 'car'],
    'recovary' => ['recovery', 'recover', 'revary'],
    'cubs'     => ['cabs'],
];

$sentence = 'i want to recovary my vehical from the cubs';
$from = array_keys($element);

foreach (createCombinations($element) as $to) {
    echo str_replace($from, $to, $sentence), "\n";
}

# => i want to recovery my vehicle from the cabs
# => i want to recover my vehicle from the cabs
# => i want to revary my vehicle from the cabs
# => i want to recovery my car from the cabs
# => i want to recover my car from the cabs
# => i want to revary my car from the cabs
