Laravel URL Helper Function: url

#url($path = null, $parameters = [], $secure = null)

The url helper function is a versatile function that can be used to generate a URL to a given path or return an instance of the configured Illuminate\Contracts\Routing\UrlGenerator implementation (by default this is an instance of Illuminate\Routing\UrlGenerator). The url function can be used to generate arbitrary URLs.

Calling the url function without any arguments returns (by default) an instance of Illuminate\Routing\UrlGenerator. Using the url function in this way is effectively the same as using the Illuminate\Support\Facades\Url facade. All of the method/function calls in the following example are equivalent:

1use Illuminate\Support\Facades\Url;
2 
3Url::action('SomeController@someAction');
4url()->action('SomeController@someAction');
5action('SomeController@someAction');

If arguments are supplied to the url helper function, it will internally make a call to the UrlGenerator instance method to, passing all the arguments along.

The following lines are equivalent:

1use Illuminate\Support\Facades\Url;
2 
3// Using the Url facade.
4Url::to('arbitraryUrl');
5 
6// Using the url helper function.
7url('arbitraryUrl');

both calls would result in the following URL:

1http://laravel.artisan/arbitraryUrl

You can also include router parameters in the generated URL by utilizing the $parameters parameter. The following function call:

1url('arbitraryUrl', ['someParameter']);

would result in the following URL being generated:

1http://laravel.artisan/arbitraryUrl/someParameter

#Generating Secure URLs

To generate secure URLs using the url helper function, supply an argument with the truth value of true to the $secure parameter. To generate secure URLs that do not require parameters simply supply an empty array [] as the argument for $parameters.

The following examples demonstrate both ways of generating secure URLs:

1url('arbitraryUrl', [], true)
2url('arbitraryUrl', ['someParameter'], true)

1https://laravel.artisan/arbitraryUrl
2https://laravel.artisan/arbitraryUrl/someParameter
