Are there any best practices or functions in PHP for generating correct GET values for URLs?

When generating GET values for URLs in PHP, it is important to properly encode the values to ensure they are correctly interpreted by the server. One common way to achieve this is by using the `http_build_query` function, which takes an associative array of parameters and returns a URL-encoded query string. This function automatically handles encoding special characters and spaces, making it a convenient and reliable method for generating GET values for URLs. 

// Example of using http_build_query to generate GET values for URLs
$params = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York'
);

$queryString = http_build_query($params);

$url = 'http://example.com/api?' . $queryString;

echo $url;
