What are the potential solutions to ensure proper URL redirection in PHP, especially when using the "a href" tag?

When using the "a href" tag in PHP to redirect users to a different URL, it's important to ensure that the URL is properly formatted and encoded to avoid errors or security vulnerabilities. One solution is to use the PHP function urlencode() to encode the URL before inserting it into the href attribute. This will ensure that special characters are properly handled and the URL is correctly redirected. 

$url = "https://example.com/page?param1=value1&param2=value2";
$encoded_url = urlencode($url);
echo '<a href="' . $encoded_url . '">Click here</a>';
