Does a String Contain Any Items From an Array (Case Insensitive)?

Checking if a String Contains Any Items from an Array (Case Insensitive)

In this programming challenge, we aim to determine whether a given string contains any of the items included in an provided array, disregarding case differences.

To address this, we can leverage the stripos() function in PHP. Here's an implementation:

function contains($str, array $arr)
{
    foreach ($arr as $a) {
        if (stripos($str, $a) !== false) {
            return true;
        }
    }
    return false;
}

Using this function, we can check if a string contains any of the items in an array as follows:

$str = 'My nAmE is Tom.';
$arr = ['name', 'tom'];
if (contains($str, $arr)) {
    // Do something to indicate that it contains
}
