PHP检查第一次出现的数组是否存在于另一个数组中

Question

I have two arrays

$setWords = array ('one','two','three');
$setSentences = array('There is one cloud in the sky', 'A dog has four legs' , 'There are three cars parked outside');

I tried the following but it didn't work.

if(array_intersect($setWords , $setSentences) == true) {
print_r($setSentences);
}

In this case it would be There is one cloud in the sky and There are three cars parked outside.

Answer 1

I love preg_grep:

$result = preg_grep('/'.implode('|', $setWords).'/', $setSentences);
print_r($result);
