How can functions like urlencode and http_build_query help in handling special characters in PHP URLs?

Special characters in URLs can cause issues with data integrity and can potentially break the URL structure. Functions like urlencode and http_build_query can help by encoding special characters in a URL-safe format, ensuring that the URL remains valid and the data is properly handled. 

// Example using urlencode function
$specialString = "Hello, World! How are you?";
$encodedString = urlencode($specialString);
echo $encodedString; // Output: Hello%2C+World%21+How+are+you%3F

// Example using http_build_query function
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York, NY'
);
$queryString = http_build_query($data);
echo $queryString; // Output: name=John+Doe&age=30&city=New+York%2C+NY
