Php 用多个单词完成一个句子

我有下面的句子

The boy is {good|better|best} in his {school|tution|class|scociety}

现在我需要创建一个递归PHP函数，该函数将把这句话作为输入，并输出如下：-

The boy is good in his school
The boy is good in his tution

good with this 4 {school|tution|class|scociety}

better with this 4 {school|tution|class|scociety}

best with this 4 {school|tution|class|scociety}

以类似的方式，我需要创建12行，因为上面的句子有12个单词。如下图所示：-

The boy is good in his school
The boy is good in his tution

good with this 4 {school|tution|class|scociety}

better with this 4 {school|tution|class|scociety}

best with this 4 {school|tution|class|scociety}

为此，我尝试了以下方法：-

function get_random($matches)
{
    $part     = substr($matches[0], 1, strlen($matches[0])-2);
    $part     = show_randomized($part);
    $rand     = array_rand($split = explode("|", $part));
    return $split[$rand];
}

function show_randomized($str)
{
    $str = preg_replace_callback('/(\{[^}]*)([^{]*\})/im', "get_random", $str);
    return $str;
}

// Test

$rand_sentence = "The boy is {good|better|best} in his {school|tution|class|scociety}";

for ($i = 0; $i < 10; $i++)
{
    echo show_randomized($rand_sentence).'<br />';
}

有什么帮助吗？

您最好在正则表达式中稍作更改，然后使用

分解

将它们放入数组，然后使用循环打印出句子

<?php
    $str = "The boy is {good|better|best} in his {school|tution|class|scociety}";
    preg_match_all("/\{([^}]+)\}/", $str, $match);
    $arr = array_map(function($value){
        return explode("|", $value);
    }, $match[1]);
    foreach($arr[0] as $adj)
        foreach($arr[1] as $name)
            echo "The boy is {$adj} in his {$name}\n";

您的正则表达式模式给出以下输出：-数组（[0]=>Array（[0]=>{good | better | best}[1]=>{school | tution | class | scociety}）[1]=>Array（[0]=>good | better | best[1]=>school | tution | class | scociety]）您应该使用：

/（？@SamSullivan我为什么要使用它？你会得到一个简单的数组，而不是多维数组，我认为这会使代码更可读（并可能节省微不足道的内存）。但我认为这没什么大不了的。@SamSullivan在这种情况下并不重要。
