php – 具有多种变体的Foreach字符串替换

我试图找出使用多个排序规则进行字符串替换的最佳方法.

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

$sentence =’我想从出租车里恢复我的车辆’;

>我想从出租车上恢复我的车辆
>我想从出租车里恢复我的车辆
>我想从出租车上取回我的车辆

代码到目前为止：

$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：扩展了另一种情况：

如果顶部数组中存在多个变体,会发生什么.

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

>我想从出租车上恢复我的车辆
>我想从出租车里恢复我的车辆
>我想从出租车中恢复我的任何东西
>我想从出租车里恢复我的车辆
>我想从出租车里恢复我的车辆
>我想从出租车里找回我的东西
>我想从出租车上取回我的车辆
>我想从出租车里复活我的车辆
>我想要从出租车里复活我的任何东西

您需要创建替换数据的所有唯一组合.对于这些组合中的每一种,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','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
