php - preg_match 字符串中的数组项？

Question

假设我有一系列坏词:

$badwords = array("one", "two", "three");

和随机字符串:

$string = "some variable text";

如何创建这个循环:

if (one or more items from the $badwords array is found in $string)
echo "sorry bad word found";
else
echo "string contains no bad words";

例子:
如果 $string = "one fine day"或 "one fine day two of us did something"，用户应该看到抱歉的坏词发现消息。
如果 $string = "fine day"，用户应该看到 string contains no bad words 消息。

据我所知，您不能从数组中preg_match。有什么建议吗？

这个怎么样:

$badWords = array('one', 'two', 'three');
$stringToCheck = 'some stringy thing';
// $stringToCheck = 'one stringy thing';

$noBadWordsFound = true;
foreach ($badWords as $badWord) {
  if (preg_match("/\b$badWord\b/", $stringToCheck)) {
    $noBadWordsFound = false;
    break;
  }
}
if ($noBadWordsFound) { ... } else { ... }
