What are some potential pitfalls to consider when creating a deadlink reporting function in PHP?

One potential pitfall to consider when creating a deadlink reporting function in PHP is ensuring that the function accurately detects and reports deadlinks without generating false positives. This can be achieved by properly validating the URLs before checking their status. Additionally, it is important to handle any potential errors or exceptions that may occur during the process to prevent the script from breaking. 

function reportDeadLink($url) {
    $headers = @get_headers($url);
    
    if ($headers && strpos($headers[0], '200') === false) {
        // Code to report deadlink
        echo "Deadlink detected: $url";
    } else {
        // Code to handle valid link
        echo "Link is valid: $url";
    }
}

// Example usage
reportDeadLink('https://example.com/invalid-page');
reportDeadLink('https://example.com/valid-page');
