PHP：在文本中查找有空格和无空格的重复单词 [英] PHP : Find repeated words with and without space in text

问题描述

  $ str ='bob是个好人。玛丽是一个好人。谁是最好的？你是个好人吗？鲍勃是最好的？ 
函数重复（$ str）
 {
 $ str = trim（$ str）; 
 $ str = ereg_replace（'[[：space：]] +'，''，$ str）; 
 $ words = explode（''，$ str）; 
 foreach（$ words为$ w）
 {
 $ wordstats [（$ w）] ++; 
 
 foreach（$ wordstats as $ k => $ v）
 {
 if（$ v> = 2）
 {
 print $ k。，; 
 
 
 
 
 
 
这就是我喜欢的结果： 
 
 
 $ b $ / p> 
 
 
  bob，good，person，is，a，the，best？ 
  
问：我如何得到结果重复的单词和空格之间的多部分单词： p> 
 
 
  bob，good，person，is，a，the，best？ ，好人，是一个好的，是的，bob是
  
 
 
解决方案
 
 <？php 
 $ str ='bob是一个好人。玛丽是一个好人。谁是最好的？你是个好人吗？鲍勃是最好的？ 
 
 //全部单词：
 $ found = str_word_count（strtolower（$ str），1）; 
 //得到所有超过1的单词
 $ counts = array_count_values（$ found）; 
 $ repeated = array_keys（array_filter（$ counts，function（$ a）{return $ a> 1;}））; 
 //以1个字的组开始结果。 
 $ results = $ repeated; 
 while（$ word = array_shift（$ found））{
 if（！in_array（$ word，$ repeated））continue; 
 $ additions = array（）; 
 while（$ add = array_shift（$ found））{
 if（！in_array（$ add，$ repeated））break; 
 $ additions [] = $ add; 
 $ count = preg_match_all（'/'。preg_quote（$ word）。'\W +'。implode（'\W +'，$ additions）。'/ si'，$ str，$ matches）; 
 if（$ count> 1）{
 $ newmatch = $ word。''.implode（''，$ additions）; 
 if（！in_array（$ newmatch，$ results））$ results [] = $ newmatch; 
} else {
 break; 
 
 
 if（！empty（$ additions））array_splice（$ found，0,0，$ additions）; 
} 
 var_dump（$ results）; 
  
收益率： 
 
  array（17）{
 [0] => 
 string（3）bob
 [1] => 
 string（2）是
 [2] => 
 string（1）a
 [3] => 
 string（4）good
 [4] => 
 string（6）person
 [5] => 
 string（3）the 
 [6] => 
 string（4）best
 [7] => 
 string（6）bob is
 [8] => 
 string（4）是
 [9] => 
 string（9）是一个好的
 [10] => 
 string（16）是个好人
 [11] => 
 string（6）good
 [12] => 
字符串（13）好人
 [13] => 
 string（11）good person
 [14] => 
 string（6）是
 [15] => 
 string（11）是最好的
 [16] => 
 string（8）best
} 
  
 
I can find repeated words in text with this function:
$str = 'bob is a good person. mary is a good person. who is the best? are you a good person? bob is the best?';
    function repeated($str)
    {
        $str=trim($str);  
        $str=ereg_replace('[[:space:]]+', ' ',$str);  
        $words=explode(' ',$str);  
        foreach($words as $w)  
        {  
        $wordstats[($w)]++;  
        }  
        foreach($wordstats as $k=>$v)  
        {  
            if($v>=2)  
            {  
                print "$k"." , ";  
            }  
        }  
    }
thats result me like :
bob , good , person , is , a , the , best?
Q : how i can get result repeated words and Multi-part words between space look like :
bob , good , person , is , a , the , best? , good person , is a , a good , is the , bob is

解决方案
<?php
$str = 'bob is a good person. mary is a good person. who is the best? are you a good person? bob is the best?';

//all words:
$found = str_word_count(strtolower($str),1);
//get all words with occurance of more then 1
$counts = array_count_values($found);
$repeated = array_keys(array_filter($counts,function($a){return $a > 1;}));
//begin results with the groups of 1 word.
$results = $repeated;
while($word = array_shift($found)){
    if(!in_array($word,$repeated)) continue;
    $additions = array();
    while($add = array_shift($found)){
        if(!in_array($add,$repeated)) break;
        $additions[] = $add;
        $count = preg_match_all('/'.preg_quote($word).'\W+'.implode('\W+',$additions).'/si',$str,$matches);
        if($count > 1){
            $newmatch = $word.' '.implode(' ',$additions);
            if(!in_array($newmatch,$results)) $results[] = $newmatch;
        } else {
            break;
        }
    }
    if(!empty($additions)) array_splice($found,0,0,$additions);
}
var_dump($results);
Yields:
array(17) {
  [0]=>
  string(3) "bob"
  [1]=>
  string(2) "is"
  [2]=>
  string(1) "a"
  [3]=>
  string(4) "good"
  [4]=>
  string(6) "person"
  [5]=>
  string(3) "the"
  [6]=>
  string(4) "best"
  [7]=>
  string(6) "bob is"
  [8]=>
  string(4) "is a"
  [9]=>
  string(9) "is a good"
  [10]=>
  string(16) "is a good person"
  [11]=>
  string(6) "a good"
  [12]=>
  string(13) "a good person"
  [13]=>
  string(11) "good person"
  [14]=>
  string(6) "is the"
  [15]=>
  string(11) "is the best"
  [16]=>
  string(8) "the best"
}
