有人有PHP代码片段来抓取字符串中的第一个“句子”吗?

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

查找后跟空格的终止字符

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

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

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

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 . '.'; 

}

我叫尤纳斯。我住在巴基斯坦。

current(explode(".",$input));

"I like stackoverflow.com."

"I like stackoverflow."

实际上,我相信你更喜欢:

试试这个:

reset(explode('.', $s, 2));
