How can special characters be replaced in URLs in PHP?

Special characters in URLs can be replaced using the urlencode() function in PHP. This function converts special characters into their URL-encoded format, allowing them to be safely used in URLs without causing issues. By using urlencode(), you can ensure that special characters are properly encoded and do not break the URL structure. 

$url = "https://example.com/page?param=" . urlencode($special_characters_string);
echo $url;
