认为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"杰克"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，或者有更好的方法？
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行尾Jack OR 后面找到一个单词。
你可以使用这个：
preg_match_all('~'bJack(?>'s+[a-z]+)?~i', $input, $matches);
print_r($matches[0]);
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);
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];
}
}
这将回显每个杰克 + 下一个单词。
