将句子分成单词 [英] Split sentence into words

问题描述

例如，我有这样的哨兵:

for example i have sentenes like this:

$text = "word, word w.d. word!..";

我需要这样的数组

Array
(
    [0] => word
    [1] => word
    [2] => w.d
    [3] => word".
)

我是新来的正则表达式.

I am very new for regular expression..

这是我尝试过的:

function divide_a_sentence_into_words($text){ 
    return preg_split('/(?<=[\s])(?<!f\s)\s+/ix', $text, -1, PREG_SPLIT_NO_EMPTY); 
}

这个

$text = "word word, w.d. word!..";
$split = preg_split("/[^\w]*([\s]+[^\w]*|$)/", $text, -1, PREG_SPLIT_NO_EMPTY);
print_r($split);

可行，但是我还有第二个问题我想用mu正则表达式写列表 "w.d"是特例.例如，这是我的列表"w.d"，"mr."，"dr."

works, but i have second question i want to write list in mu regular exppression "w.d" is special case.. for example this words is my list "w.d" , "mr.", "dr."

如果我要输入文字:

$ text =单词，单词博士w.d. word！..";

$text = "word, dr. word w.d. word!..";

我需要数组:

Array (
  [0] => word
  [1] => dr.
  [2] => word
  [3] => w.d
  [4] => word 
)

抱歉英语不好...

推荐答案

使用正则表达式为/[^\w]*([\s]+[^\w]*|$)/的preg_split应该可以正常工作:

Using preg_split with a regex of /[^\w]*([\s]+[^\w]*|$)/ should work fine:

<?php
    $text = "word word w.d. word!..";
    $split = preg_split("/[^\w]*([\s]+[^\w]*|$)/", $text, -1, PREG_SPLIT_NO_EMPTY);
    print_r($split);
?>

演示

输出:

Array
(
    [0] => word
    [1] => word
    [2] => w.d
    [3] => word
)
