有没有人有代码字符串中抓住了第一个“句”一个PHP代码片段？(Does anyone have a

如果我有一个类似的说明：

“我们更希望能得到解答，而不仅仅是讨论的问题。提供细节。写清楚和简单。”

和所有我想要的是：

“我们更希望能得到解答，而不仅仅是讨论的问题。”

我想我会寻找一个正则表达式，如“[！\？]”，决定对strpos然后执行从主字符串SUBSTR，但我想它是做一个平常的事，所以希望有人有一个片段躺在周围。

Answer 1:

稍微更昂贵的表情，如果你想选择多种类型的标点符号作为句子终止但会更加适应。

$sentence = preg_replace('/([^?!.]*.).*/', '\\1', $string);

查找结束符后面有一个空格

$sentence = preg_replace('/(.*?[?!.](?=\s|$)).*/', '\\1', $string);

Answer 2:

<?php
$text = "We prefer questions that can be answered, not just discussed. Provide details. Write clearly and simply.";
$array = explode('.',$text);
$text = $array[0];
?>

Answer 3:

我以前的正则表达式似乎在测试而不是在实际PHP工作。我已编辑这个答案提供全面，工作PHP代码，以及改进的正则表达式。

$string = 'A simple test!';
var_dump(get_first_sentence($string));

$string = 'A simple test without a character to end the sentence';
var_dump(get_first_sentence($string));

$string = '... But what about me?';
var_dump(get_first_sentence($string));

$string = 'We at StackOverflow.com prefer prices below US$ 7.50. Really, we do.';
var_dump(get_first_sentence($string));

$string = 'This will probably break after this pause .... or won\'t it?';
var_dump(get_first_sentence($string));

function get_first_sentence($string) {
    $array = preg_split('/(^.*\w+.*[\.\?!][\s])/', $string, -1, PREG_SPLIT_DELIM_CAPTURE);
    // You might want to count() but I chose not to, just add   
    return trim($array[0] . $array[1]);
}

Answer 4:

试试这个：

$content = "My name is Younas. I live on the pakistan. My email is **fromyounas@gmail.com** and skype name is "**fromyounas**". I loved to work in **IOS development** and website development . ";

$dot = ".";

//find first dot position     

$position = stripos ($content, $dot); 

//if there's a dot in our soruce text do

if($position) { 

    //prepare offset

    $offset = $position + 1; 

    //find second dot using offset

    $position2 = stripos ($content, $dot, $offset); 

    $result = substr($content, 0, $position2);

   //add a dot

   echo $result . '.'; 

}

输出是：
