Question

可能重复：
Remove entire word if the word contains specific string

如何删除包含单词的整个单词？例如，'releas'应该删除已发布的，释放发布等。

/* Read in from the file here, not in the function - you only need to read the file once */
$wordlist = array('release','announce');

/* Sample data */
$words = 'adobe releases releases Acrobat X';

foreach ($wordlist as $v)
      $words = clean($v,$words);

function clean($wordlist,$value)
{
        return preg_replace("/\b$wordlist\b/i", '***',trim($value));
}  

echo 'Words: '.$words.PHP_EOL;

Answer 1

我会使用这个REGEXP;

return preg_replace("/\w*$wordlist\w*/i", '***', trim($value));

应用于您的代码，它将是：

foreach ($wordlist as $v)
  $words = clean($v, $words);

function clean($word, $value) {
    return preg_replace("/\w*$word\w*/i", '***',trim($value));
}

（请注意我已将$wordlist重命名为$word以使事情更清晰，因为$wordlist也是数组的名称）

Answer 2

您可以循环浏览$wordlist

function clean($wordlist,$value)
{
    foreach ($wordlist as $word) {
        $value = preg_replace("/\b\w*$word\w*\b/i", '***', trim($value));
    }

    return $value;
}

并在一次替换

function clean($wordlist,$value)
{
    $all_words = implode('|', $wordlist);
    return preg_replace("/\b\w*(?:$all_words)\w*\b/i", '***', trim($value));
}

更新：

通过其他答案和评论，我似乎无法正确看待这个问题。如果$wordlist 不是数组，您可以使用@ fthiella的答案。

Answer 3

以这种方式试试

$_words = implode( '|', $wordlist );

return preg_replace( "/\b\w*{$_words}\w*\b/i", "***", trim( $value ) );

或更好

$_words = array();
foreach ( $wordlist as $word ) {
    $_words[] = '/\b\w*' . preg_quote( $word ) . '\w*\b/i';
}

return preg_replace( $_words, '***', trim( $value ) );

第二种方法避免了正则表达式的问题，如果一些保留的字符出现在单词内。

如果包含单词，则删除整个单词
