What are the potential pitfalls of using strpos function in PHP to search for a value within a string?

One potential pitfall of using the strpos function in PHP to search for a value within a string is that it returns false if the value is not found, which can lead to unexpected results if not handled properly. To solve this issue, you can explicitly check for false using strict comparison (===) and handle it accordingly in your code. 

$string = "Hello, World!";
$search = "World";

$pos = strpos($string, $search);

if ($pos !== false) {
    echo "Found '$search' at position $pos";
} else {
    echo "'$search' not found in the string";
}
