How does the urlencode() function in PHP help in encoding variable contents for use in URLs?

When passing variable contents in URLs, special characters such as spaces or symbols can cause issues. The urlencode() function in PHP helps by encoding these characters into a format that can be safely passed in a URL. This ensures that the variable contents are correctly interpreted by the server when the URL is accessed. 

// Variable containing content to be passed in URL
$content = "Hello, World!";

// Encoding the variable contents for use in URL
$encoded_content = urlencode($content);

// Output the encoded content
echo $encoded_content;
