Are there any best practices for implementing URL parsing and comparison in PHP for navigation purposes?

When implementing URL parsing and comparison in PHP for navigation purposes, it is important to properly sanitize and validate the URLs to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One best practice is to use PHP's built-in functions like parse_url() to parse the URL components and compare them using strict comparison operators to ensure accurate navigation. 

// Example of parsing and comparing URLs for navigation purposes

// Sample current URL
$currentUrl = "https://www.example.com/page";

// Sample target URL to compare
$targetUrl = "https://www.example.com/page";

// Parse the URLs
$currentUrlParts = parse_url($currentUrl);
$targetUrlParts = parse_url($targetUrl);

// Compare the parsed URL components
if($currentUrlParts['scheme'] === $targetUrlParts['scheme'] &&
   $currentUrlParts['host'] === $targetUrlParts['host'] &&
   $currentUrlParts['path'] === $targetUrlParts['path']) {
    // URLs match, perform navigation logic here
    echo "Navigating to target URL";
} else {
    // URLs do not match
    echo "URLs do not match";
}
