    if (!filter_var($service, FILTER_VALIDATE_URL) === false) {
        $service = $service;
    } else {
        $service = '<a href='.$service.'>'.$service.'</a>';
    }
    echo $service;
endforeach;

Answer 1

The problem here is with the following statement:

if (!filter_var($service, FILTER_VALIDATE_URL) === false)
    ^                                              ^^^^^

You're using a double negative here, being the ! operator which means "not" and you're using "false".

Either remove the ! or change the "false" to "true".

You're also going to need to add http:// to the url you wish to use in order to validate properly.

$services=array('Bakery','www.google.com');

will fail for the Google link. If you want it to validate, you will need to change it to:

$services=array('Bakery','http://www.google.com');
