将文本拆分成单词问题PHP，复杂的问题 [英] Split text into words problem PHP, complicated problem

问题描述

我正在尝试将文本拆分为单词:

I am trying to split the text into words:

$delimiterList = array(" ", ".", "-", ",", ";", "_", ":",
           "!", "?", "/", "(", ")", "[", "]", "{", "}", "<", ">", "\r", "\n",
           '"');
$words = mb_split($delimiterList, $string);

在字符串上可以很好地工作，但是在某些情况下我不得不处理数字.

which works quite fine with strings but I am stuck in some cases where I have to do with numbers.

例如如果我有文字看看这个.我的分数是3.14，对此我感到高兴". 现在数组是

E.g. If I have the text "Look at this.My score is 3.14, and I am happy about it.". Now the array is

[0]=>Look,
[1]=>at,
[2]=>this,
[3]=>My,
[4]=>score,
[5]=>is,
[6]=>3,
[7]=>14,
[8]=>and, ....

然后将3.14分为3和14，在我的情况下不应该发生. 我的意思是，点应该分开两个字符串，而不是两个数字. 应该是这样的:

Then also the 3.14 is divided in 3 and 14 which should not happen in my case. I mean point should divide two strings but not two numbers. It should be like:

[0]=>Look,
[1]=>at,
[2]=>this,
[3]=>My,
[4]=>score,
[5]=>is,
[6]=>3.14,
[7]=>and, ....

但是我不知道如何避免这种情况！

But I have no Idea how to avoid this cases!

有人知道如何解决这个问题吗?

Anybody any idea how to solve this problem?

推荐答案

或使用正则表达式:)

<?php
$str = "Look at this.My score is 3.14, and I am happy about it.";

// alternative to handle Marko's example (updated)
// /([\s_;?!\/\(\)\[\]{}<>\r\n"]|\.$|(?<=\D)[:,.\-]|[:,.\-](?=\D))/

var_dump(preg_split('/([\s\-_,:;?!\/\(\)\[\]{}<>\r\n"]|(?<!\d)\.(?!\d))/',
                    $str, null, PREG_SPLIT_NO_EMPTY));

array(13) {
  [0]=>
  string(4) "Look"
  [1]=>
  string(2) "at"
  [2]=>
  string(4) "this"
  [3]=>
  string(2) "My"
  [4]=>
  string(5) "score"
  [5]=>
  string(2) "is"
  [6]=>
  string(4) "3.14"
  [7]=>
  string(3) "and"
  [8]=>
  string(1) "I"
  [9]=>
  string(2) "am"
  [10]=>
  string(5) "happy"
  [11]=>
  string(5) "about"
  [12]=>
  string(2) "it"
}
