Question

我想将一个句子分成一个段落，每个段落应该少于几个单词。例如：

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. 

Paragraph 1: 
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.

Paragraph 2: 
Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.

在上面的例子中，小于20的单词在段落1中，其余的在段落2上。

有没有办法用php实现这个目的？

我已经尝试了$abc = explode(' ', $str, 20);，它会在一个数组中存储20个单词，然后其余部分将在数组$ abc [＆＃39; 21＆＃39;]中存储。我如何从前20个数组中提取数据作为第一段，然后将其余数据作为第二段？

Answer 1

首先将字符串拆分成句子。然后循环遍历句子数组，首先将句子添加到paragraph数组中，然后计算paragraph数组中该单词的单词，如果大于19的增量段落计数器。

$string = 'Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.';

$sentences = preg_split('/(?<=[.?!;])\s+(?=\p{Lu})/', $string);

$ii = 0;
$paragraphs = array();
foreach ( $sentences as $value ) {
    if ( isset($paragraphs[$ii]) ) { $paragraphs[$ii] .= $value; }
    else { $paragraphs[$ii] = $value; }
    if ( 19 < str_word_count($paragraphs[$ii]) ) {
        $ii++;
    }
}
print_r($paragraphs);

输出：

Array
(
    [0] => Contrary to popular belief, Lorem Ipsum is not simply random text.It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
    [1] => Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.
)
