输出随机单词 [英] Output random words

问题描述

我必须写一个程序，将输出随机单词（随机字母），而且不会有3人声或接近辅音，所以我写了：

I have to write a program that will output random words(with random letters) and that will not have 3 vocals or consonants near, so i wrote:

$array = array();                                 
$n = 10;                                               

for($i = 0; $i < $n; $i++) {
    $l = rand(4, 10);  //$l = word length
?>

<br>

<?

for ($j = 0; $j < $l; $j++) {

    $cas = rand(65, 90);  //$cas=random letters
    $array[$j] = $cas; 

    if($j > 1) {    
        if (($array[$j-1] == 65 || $array[$j-1] == 69 || $array[$j-1] == 73 || $array[$j-1] == 79 || $array[$j-1] == 85) ^ ($array[$j-2] == 65|| $array[$j-2] == 69 || $array[$j-2] == 73 || $array[$j-2] == 79 || $array[$j-2] == 85)) {  //will do XOR '^'

            $cas = rand(65, 90);                                                           
            $array[$j] = $cas;                          

        }

    }

    $m = chr($array[$j]);   
    echo $m;
    }
}


?>

不知道为什么，但看来，如果不工作，因为当它输出，它会同时打印的话在3以上的辅音或发声。
有谁能够帮助我？感谢：D和英语不好对不起：P

don't know why but it seems that IF doesn't work, 'because when it outputs it'll print also words with 3 or more consonants or vocal. Can anybody help me? thanks :D and sorry for bad english :P

推荐答案

这应该为你工作：

所以，你有什么我所做的一切？

So what have I done here?

在第一部分中我已经定义了其中包含的所有字符数组 $字符例如 [A-ZA-Z] 。然后我也有 $元音包含例如，全元音 [aAeEiIoOuU] 。而且我也定义 $辅音包含所有辅音。

In the first part I have defined the array $characters which contains all characters e.g.[a-zA-Z]. Then I also have $vowels which contains all vowels e.g. [aAeEiIoOuU]. And I also defined $consonants which contains all consonants.

这之后，我混整个 $字符阵列的 洗牌（） 并把 $长度从一开始就与<一个数组元素HREF =htt​​p://php.net/manual/en/function.array-slice.php相对=nofollow> array_slice（） 。

After this I mixed the entire $characters array with shuffle() and took $length array elements from the start with array_slice().

然后我检查了 $ randomWord 通过功能检查（），其中经过随机的每一个字符字，并检查是否在接下来的3个字符或者是元音或辅音。我这样做与 in_array（） 检查字符是在关联数组如 $元音或 $辅音。如果是的话我更改行的中间人物到对面的如元音 - > 辅音 | 辅音 - > 元音。如果没有行无论是元音辅音还是被发现则返回随机字。

Then I checked the $randomWord with the function check(), which goes through each character of the random word and checks if the next 3 characters are either vowels or consonants. I do this with in_array() to check if the character is in the associated array e.g. $vowels or $consonants. If yes I change middle character of the row to the opposite e.g. vowels -> consonants | consonants -> vowels. And if no row either of vowels or consonants are found it returns the random word.

最后我只使用 array_map（） 与 CHR（） 要经过每个数组元素，并将其从ASCII更改为匹配的字符。

At the end I just use array_map() with chr() to go through each array element and change it from ASCII to the matching character.

要打印出来我用 破灭（） 每个字符一起追加。

To print it I used implode() to append each character together.

<?php

    $characters = array_merge(range(65, 90), range(97, 122));
    $vowels = array(65, 97, 69, 101, 73, 105, 79, 111, 85, 117);
    $consonants  = array(66, 98, 67, 99, 68, 100, 70, 102, 71, 103, 72, 104, 74, 106, 75, 107, 76, 108, 77, 109, 78, 110, 80, 112, 81, 113, 82, 114, 83, 115, 84, 116, 86, 118, 87, 119, 88, 120, 89, 121, 90, 122);
    $randomWord = "";
    $length = rand(4, 10);

    shuffle($characters);
    $randomWord = array_slice($characters, 0, $length);

    function check($randomWord, $vowels, $consonants) {

        foreach($randomWord as $key => $randomCharacter) {

            //Check for vowels
            if(in_array($randomWord[$key], $vowels) && ( isset($randomWord[$key+1]) && in_array($randomWord[$key+1], $vowels) ) && ( isset($randomWord[$key+2]) && in_array($randomWord[$key+2], $vowels) )) {
                $randomWord[$key+1] = $consonants[array_rand($consonants, 1)];
                check($randomWord, $vowels, $consonants);   
            } 

            //Check for consonants
            if(in_array($randomWord[$key], $consonants) && ( isset($randomWord[$key+1]) && in_array($randomWord[$key+1], $consonants) ) && ( isset($randomWord[$key+2]) && in_array($randomWord[$key+2], $consonants) )) {
                $randomWord[$key+1] = $vowels[array_rand($vowels, 1)];
                check($randomWord, $vowels, $consonants);
            } 

        }

        return $randomWord;     
    }

    $randomWord = check($randomWord, $vowels, $consonants);
    echo $randomWord = implode("", array_map("chr", $randomWord));

?>

示例输出：
