PHP字符串循环，并加入

给定一个字符串，如“疯狂农场，农民，FOX，HEN，拖拉机”（注意字符串是按字母顺序排列）PHP字符串循环，并加入

将如何通过串一个循环，并创建一个数组str中[]下面？注意数组键也是按字母顺序排列的，这有助于消除重复的两个或X-num字连接，我相信？

str[BARNYARD] = BARNYARD 
str[FARMER] = FARMER 
str[FOX] = FOX 
str[HEN] = HEN 
str[TRACTOR] = TRACTOR 
str[BARNYARDFARMER] = BARNYARD FARMER 
str[BARNYARDFOX] = BARNYARD FOX 
str[BARNYARDHEN] = BARNYARD HEN 
str[BARNYARDTRACTOR] = BARNYARD TRACTOR 
str[FARMERFOX] = FARMER FOX 
str[FARMERHEN] = FARMER HEN 
str[FARMERTRACTOR] = FARMER TRACTOR 
str[FOXHEN] = FOX HEN 
str[FOXTRACTOR] = FOX TRACTOR 
str[HENTRACTOR] = HEN TRACTOR 
str[BARNYARDFARMERFOX] = BARNYARD FARMER FOX 
str[BARNYARDFOXHEN] = BARNYARD FOX HEN 
str[BARNYARDHENTRACTOR] = BARNYARD HEN TRACTOR 
str[FARMERFOXHEN] = FARMER FOX HEN 
str[FARMERHENTRACTOR] = FARMER HEN TRACTOR 
str[FOXHENTRACTOR] = FOX HEN TRACTOR 
str[BARNYARDFARMERFOXHEN] = BARNYARD FARMER FOX HEN 
str[BARNYARDFOXHENTRACTOR] = BARNYARD FOX HEN TRACTOR 
str[FARMERFOXHENTRACTOR] = FARMER FOX HEN TRACTOR 
str[BARNYARDFARMERFOXHENTRACTOR] = BARNYARD FARMER FOX HEN TRACTOR

您确定输出已完成或缺少什么吗？例如。我没有看到'BARNYARD FARMER HEN'和'FARMER FOX TRACTOR'等。 – 2012-02-15 09:31:38

这段代码背后有原因还是这个作业？ – j08691 2012-02-15 19:05:30

$str_array = explode(','. $string); 
//sort($str_array); // or ksort($str_array); 
// if you need the text as array_keys, try in combination with array_flip() 
foreach ($str_array AS $single_str) { 
    echo trim($single_str).'<br />'; 
}

$chars=explode(",",$string);

另一个问题请参见本solution。这可以使用全局$ arr进行修改。 $ chars数组的赋值应该是global $chars;该空格必须保留。现在拍下echo $uj.'<br />';并更改为$strl=str_replace(" ","",$uj); $strk=substr($uj,0,strlen($uj)-1); $str[$strl]=$strk;

P.S.我知道全球并不好，但它是最简单的方法。

除了你的起始字符串是错误的。 – j08691 2012-02-14 18:27:43

@ j08691我已经完成了这项工作，按照排序顺序进行......没有错，按照提问 – 2012-02-14 18:30:18

您的结果甚至不是OP所需要的。 – j08691 2012-02-14 19:23:46

所以你想要你的字符串中的单词的所有排列？

只是做了一个小的后期处理上的代码的PHP网站这个伟大的片断：http://www.php.net/manual/en/function.shuffle.php#90615

$in = explode(',', str_replace(' ', '', 'BARNYARD, FARMER, FOX, HEN, TRACTOR')); 
$power_perms = power_perms($in); 

$temp = array(); 

foreach($power_perms as $sets) 
{ 
    $temp[ implode('', $sets) ] = implode(' ', $sets); 
} 

asort($temp); 

print '<pre>'. print_r($temp, true) .'</pre>'; 

function power_perms($arr) 
{ 
    $power_set = power_set($arr); 
    $result = array(); 
    foreach($power_set as $set) { 
     $perms = perms($set); 
     $result = array_merge($result, $perms); 
    } 
    return $result; 
} 

function power_set($in, $minLength = 1) 
{ 

    $count = count($in); 
    $members = pow(2, $count); 
    $return = array(); 
    for($i = 0; $i < $members; $i++) { 
     $b = sprintf("%0" . $count . "b", $i); 
     $out = array(); 
     for($j = 0; $j < $count; $j++) { 
      if($b{$j} == '1') 
       $out[] = $in[$j]; 
     } 
     if(count($out) >= $minLength) { 
      $return[] = $out; 
     } 
    } 

    //usort($return,"cmp"); //can sort here by length 
    return $return; 
} 

function factorial($int) 
{ 
    if($int < 2) { 
     return 1; 
    } 

    for($f = 2; $int - 1 > 1; $f *= $int--) 
     ; 

    return $f; 
} 

function perm($arr, $nth = null) 
{ 

    if($nth === null) { 
     return perms($arr); 
    } 

    $result = array(); 
    $length = count($arr); 

    while($length--) { 
     $f = factorial($length); 
     $p = floor($nth/$f); 
     $result[] = $arr[$p]; 
     array_delete_by_key($arr, $p); 
     $nth -= $p * $f; 
    } 

    $result = array_merge($result, $arr); 
    return $result; 
} 

function perms($arr) 
{ 
    $p = array(); 
    for($i = 0; $i < factorial(count($arr)); $i++) { 
     $p[] = perm($arr, $i); 
    } 
    return $p; 
} 

function array_delete_by_key(&$array, $delete_key, $use_old_keys = FALSE) 
{ 

    unset($array[$delete_key]); 

    if(!$use_old_keys) { 
     $array = array_values($array); 
    } 

    return TRUE; 
}

如果使用PEAR是一个选项，你会发现Math_Combinatorics类有用：

<?php 
$input = array("BARNYARD", "FARMER", "FOX", "HEN", "TRACTOR"); 
$words = array(); 
require_once("Math/Combinatorics.php"); 
$combinatorics = new Math_Combinatorics; 
for($i = 1; $i <= count($input); $i++) { 
    $combinations = $combinatorics->combinations($input, $i); 
    foreach($combinations as $combination) { 
     $key = implode("", $combination); 
     $val = implode(" ", $combination); 
     $words[$key] = $val; 
    } 
} 
print_r($words);

输出

Array
