在php中的句子中找到一个单词

Question

I have this sentence:

$newalt="My name is Marie";

I want to include a page if marie or josh is found:

$words = array("marie", "josh");

$url_string = explode(" ", $newalt);

if(!in_array($url_string, $words)){
    echo "marie or josh are not in array";
}

the problem is, when I run this php it shows "marie or josh are not in array" and marie is the array (or should be). What is wrong?

Answer 1

The solution using array_intersect and array_map functions:

$newalt = "My name is Marie";
$words = ["marie", "josh"];

$url_string = explode(" ", $newalt);

if (empty(array_intersect($words, array_map("strtolower", $url_string)))) {
    echo "marie or josh are not in array";
}
