In what scenarios would using stripos() be more advantageous than preg_grep in PHP?

Using stripos() would be more advantageous than preg_grep in scenarios where you simply need to check if a substring exists within a string without the need for complex pattern matching. stripos() is faster and more efficient for simple substring searches compared to the regular expression capabilities of preg_grep. 

$string = "Hello, World!";
$substring = "world";

if (stripos($string, $substring) !== false) {
    echo "Substring found!";
} else {
    echo "Substring not found.";
}
