如何为php函数添加拼写检查

Question

我是编码新手，我一直在寻找一个脚本来创建 Anagrams 列表，我正在使用以下脚本，但它将显示由每个可能的组合组成的单词列表。

我想向函数添加拼写检查，例如我在此处找到的 pspell_check() 访问https://www.php.net/manual/en/function.pspell-check.php

这个想法是只显示英语词典中的单词。

如果有人能告诉我如何向此代码添加拼写检查，将不胜感激。

<?php 

// PHP program to print all  

// permutations of a given string. 

/** 

* permutation function 

* @param str string to  

*  calculate permutation for 

* @param l starting index 

* @param r end index 

*/

function permute($str, $l, $r) 

{ 

    if ($l == $r) 

        echo $str. "\n"; 

    else

    { 

        for ($i = $l; $i <= $r; $i++) 

        { 

            $str = swap($str, $l, $i); 

            permute($str, $l + 1, $r); 

            $str = swap($str, $l, $i); 

        } 

    } 

} 

/** 

* Swap Characters at position 

* @param a string value 

* @param i position 1 

* @param j position 2 

* @return swapped string 

*/

function swap($a, $i, $j) 

{ 

    $temp; 

    $charArray = str_split($a); 

    $temp = $charArray[$i] ; 

    $charArray[$i] = $charArray[$j]; 

    $charArray[$j] = $temp; 

    return implode($charArray); 

} 

// Driver Code 

$str = "ANAGRAM"; 

$n = strlen($str); 

permute($str, 0, $n - 1); 

// This code is contributed by mits. 

?>
