如何分割文本以匹配雙引號加尾隨文本到點？

Question

我怎樣才能得到一個雙引號的句子，其中有一個點必須拆分？

實例文檔是這樣的：

「國際象棋可以幫助我們克服困難和痛苦，」 Unnikrishnan說，以我的皇后。 「在棋盤上，你正在戰鬥。因爲我們也在與日常生活中的艱辛搏鬥。「他說。

我想輸出是這樣的：

Array 
(
    [0] =>"Chess helps us overcome difficulties and sufferings," said Unnikrishnan, taking my queen. 
    [1] =>"On a chess board you are fighting. as we are also fighting the hardships in our daily life," he said. 
) 

我的代碼仍然用點爆炸。

function sample($string) 
{ 
    $data=array(); 
    $break=explode(".", $string); 
    array_push($data, $break); 

    print_r($data); 
} 

我仍然困惑分體式兩種分隔符關於雙引號和點。因爲在雙引號內有一個包含點分隔符的句子。

Answer 1

這裏是使用由preg_split()隨後preg_replace()以固定左和右雙引號了一個更簡單的模式（Demo）：

$in='「Chess helps us overcome difficulties and sufferings,」 said Unnikrishnan, taking my queen. 「On a chess board you are fighting. as we are also fighting the hardships in our daily life.」 he said.'; 

$out=preg_split('/ (?=「)/',$in,null,PREG_SPLIT_NO_EMPTY); 

$find='/[「」]/u'; // unicode flag is essential 
$replace='"'; 
$out=preg_replace($find,$replace,$out); // replace curly quotes with standard double quotes 

var_export($out); 

輸出：

array (
    0 => '"Chess helps us overcome difficulties and sufferings," said Unnikrishnan, taking my queen.', 
    1 => '"On a chess board you are fighting. as we are also fighting the hardships in our daily life." he said.', 
) 

preg_split()的空間，隨後通過匹配一個「（左雙引號）。

0123'步驟需要使用u修飾符的模式以確保識別字符類中的左右雙引號。使用'/「|」/'意味着您可以刪除u修飾符，但它使正則表達式引擎必須執行的步驟加倍（對於這種情況，我的字符類僅使用189步與使用372步的管道字符相比）。

而且關於preg_split()和preg_match_all()之間的選擇，去與preg_split()的原因是因爲其目標是僅僅各執後跟一個left double quote空間的字符串。如果目標是省略不與分隔空間字符相鄰的子字符串，則preg_match_all()將是更實際的選擇。

$out=preg_match_all('/「.+?(?= 「|$)/',$in,$out)?$out[0]:null; 

Answer 2

一個很好的例子爲(*SKIP)(*FAIL)：

「[^「」]+」(*SKIP)(*FAIL)|\.\s* 
# looks for strings in double quotes 
# throws them away 
# matches a dot literally, followed by whitespaces eventually 

---

在 PHP：

$regex = '~「[^「」]+」(*SKIP)(*FAIL)|\.\s*~'; 
$parts = preg_split($regex, $your_string_here); 

這產生

Array 
(
    [0] => 「Chess helps us overcome difficulties and sufferings,」 said Unnikrishnan, taking my queen 
    [1] => 「On a chess board you are fighting. as we are also fighting the hardships in our daily life.」 
) 

見a demo on regex101.com以及a demo on ideone.com。

Answer 3

或者：

regex101^（16步）

儘管我的邏輯，如果你仍然想使用preg_match_all()，我preg_split()線可以被替換

「.[^」]+」(?:.[^「]+)?

• 「.[^」]+」匹配「和」之間的一切。
• (?:.[^「]+)?比賽 - 的可能性，這是爲什麼還有最後? - 一切，這不是一個開始「，?:意味着非捕獲組。

PHP - PHPfiddle： - 點擊 「運行F9」 - [更新替換「，」與"]

<?php 
    $str = '「Chess helps us overcome difficulties and sufferings,」 said Unnikrishnan, taking my queen. 「On a chess board you are fighting. as we are also fighting the hardships in our daily life.」'; 

if(preg_match_all('/「.[^」]+」(?:.[^「]+)?/',$str, $matches)){ 
    echo '<pre>'; 
    print_r(preg_replace('[「|」]', '"', $matches[0])); 
    echo '</pre>'; 
} 
?> 

輸出：

Array 
(
    [0] => "Chess helps us overcome difficulties and sufferings," said Unnikrishnan, taking my queen. 
    [1] => "On a chess board you are fighting. as we are also fighting the hardships in our daily life." 
)
