我已经接近我想要的东西了。我遇到了一些逻辑问题，如果结果等于或与所述结果相反，则不显示结果。我正在寻找两个美国州名的字谜，它们是其他两个州名的字谜。我找到了解决方案，现在它真的只是一个显示问题........我想。任何帮助将不胜感激。谢谢你。

<?php
ini_set('max_execution_time', 300);
function anagramOf ($array, $start, $len) 
{
    global $i;
    $word = implode ("", $array);
    $i = ++$i;
    printf ("%'.-20d%'.20s%s", $i, ucfirst($word), "<BR>  \n");
}

function sortstr ($astring)
{
    global $word, $s, $l;
    $s = strtolower ($astring);
    $array = preg_split ('//', $s, -1, PREG_SPLIT_NO_EMPTY);
    sort ($array);
    $s = implode ("", $array);
}

function search ($aword,$pairs)
{
    global $len, $word, $s, $i;

    $size = count ($pairs);
    for ($k = 0; $k < $size; $k++)
    {
    $pairs[$k] = chop ($pairs[$k]);
        if (strlen ($pairs[$k]) == $len)
        {
            $l = $pairs[$k];
            sortstr ($l);
            $ls = $s;

            if (!strcmp ($ls, $word))

            }                       
        }
    }
}

所以最大的问题是你将各州联合起来的方式。在您匹配的州列表中，您匹配的是 AlabamaAlaska 和 AlaskaAlabama。所以一件好事是只匹配唯一的两个状态组合。

$doubleStates = array();

for ($i = 0, $max = count($states); $i < $max; $i++) {
    // The first loop starts from the first element of the array
    for ($j = $i + 1; $j < $max; $j++) {
        // The second loop starts from the next element of the first loop
        $doubleStates[] = $states[$i] . $states[$j];
    }
}

我可能不应该为您编写所有代码，但我被带走了：

<?php

function findAnagrams($array) {
    do {
        $matcher = null;
        $matches = array();
        foreach ($array as $key => $val) {
            if (is_null($matcher)) {
                unset($array[$key]);
                $matcher = $val;
            } elseif (isAnagram($matcher, $val)) {
                if (empty($matches)) {
                    $matches[] = $matcher;
                }
                $matches[] = $val;
            }
        }

        if (count($matches) > 0) {
            print_r($matches);
            echo "<br >";
        }
    } while (count($array) > 0);
}

function isAnagram($a, $b) {
    return letterize($a) == letterize($b);
}

function letterize($a) {
    $array = str_split(str_replace(' ', '', strtolower($a)));
    sort($array);
    return join($array);
}

$states = array('Alabama','Alaska','Arizona','Arkansas','California','Colorado',
    'Connecticut','Delaware','Florida','Georgia','Hawaii','Idaho','Illinois',
    'Indiana','Iowa','Kansas','Kentucky','Louisiana','Maine','Maryland',
    'Massachusetts','Michigan','Minnesota','Mississippi','Missouri','Montana',
    'Nebraska','Nevada','New Hampshire','New Jersey','New Mexico','New York',
    'North Carolina','North Dakota','Ohio','Oklahoma','Oregon','Pennsylvania',
    'Rhode Island','South Carolina','South Dakota','Tennessee','Texas','Utah',
    'Vermont','Virginia','Washington','West Virginia','Wisconsin','Wyoming');

$doubleStates = array();

for ($i = 0, $max = count($states); $i < $max; $i++) {
    for ($j = $i + 1; $j < $max; $j++) {
        $doubleStates[] = $states[$i] . $states[$j];
    }
}

findAnagrams($doubleStates);
