Are there any potential pitfalls to using the strpos function in PHP for string manipulation?

One potential pitfall of using the strpos function in PHP for string manipulation is that it returns false if the substring is not found in the string, which can lead to unexpected behavior if not handled properly. To solve this issue, you can explicitly check for false using the strict comparison operator (===) and handle the case where the substring is not found. 

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

$position = strpos($string, $substring);

if ($position !== false) {
    echo "Substring found at position: " . $position;
} else {
    echo "Substring not found";
}
