Question

想想我有一个包含以下内容的文本文件：

Hello my name is Jack Jordon. What is your name? Let there be a party. Is your name Jack Marais, I didn't think so Jack van Riebeeck. Good day Jack.

如何使用PHP找到所有“Jack”单词及其后面的单词？

所以结果将是

Jack Jordon
Jack Marais
Jack van
Jack

是否可以使用正则表达式执行此操作，还是有更好的方法？

Answer 1

您可以在preg_match_all中使用此正则表达式：

'/\bJack\s+(?:\s+\w+|$)/'

此正则表达式只会在Jack或行结束后找到一个单词。

Answer 2

您可以使用：

preg_match_all('~\bJack(?>\s+[a-z]+)?~i', $input, $matches);
print_r($matches[0]);

Answer 3

试试：

$input  = 'Hello my name is Jack Jordon. What is your name? Let there be a party. Is your name Jack Marais, I didn\'t think so Jack van Riebeeck. Good day Jack.';
$search = 'Jack';

preg_match_all('/(' . $search . '[a-z ]*[A-Z][a-z]+)/', $input, $matches);
$output = $matches[0];
var_dump($output);

Answer 4

试试这个：

$yourSentend = "Hello my name is Jack Jordon. What is your name? Let there be a party. Is your name Jack Marais, I didn't think so Jack van Riebeeck. Good day Jack.";
$words = explode(' ', $yourSentence);
for ($i = 0, $m = count($words); $i < $m; $i++) {
    if ($words[$i] == 'Jack') {
        echo $words[$i].' '.$words[$i+1];
    }
}

这将回应每个杰克+下一个词。
