composer require josantonius/cookie --prefer-source

You can also clone the complete repository with Git:

Exceptions Used

use Josantonius\Cookie\Exceptions\CookieException;

Usage

Example of use for this library:

Create Cookie instance with default options

use Josantonius\Cookie\Cookie;

$cookie = new Cookie();

use Josantonius\Cookie\Facades\Cookie;

Cookie::options();

Create Cookie instance with custom options

use Josantonius\Cookie\Cookie;

$cookie = new Cookie(
    domain: 'example.com',
    expires: time() + 3600,
    httpOnly: true,
    path: '/foo',
    raw: true,
    sameSite: 'Strict',
    secure: true,
);

use Josantonius\Cookie\Facades\Cookie;

Cookie::options(
    expires: 'now +1 hour',
    httpOnly: true,
);

Sets a cookie by name

use Josantonius\Cookie\Cookie;

$cookie = new Cookie();

$cookie->set('foo', 'bar');

use Josantonius\Cookie\Facades\Cookie;

Cookie::set('foo', 'bar');

Sets a cookie by name modifying the expiration time

use Josantonius\Cookie\Cookie;

$cookie = new Cookie();

$cookie->set('foo', 'bar', time() + 3600);

use Josantonius\Cookie\Facades\Cookie;

Cookie::set('foo', 'bar', new DateTime('now +1 hour'));

Sets several cookies at once

use Josantonius\Cookie\Cookie;

$cookie = new Cookie();

$cookie->replace([
    'foo' => 'bar',
    'bar' => 'foo'
]);

use Josantonius\Cookie\Facades\Cookie;

Cookie::replace([
    'foo' => 'bar',
    'bar' => 'foo'

    'foo' => 'bar',
    'bar' => 'foo'
], time() + 3600);

use Josantonius\Cookie\Facades\Cookie;

Cookie::replace([
    'foo' => 'bar',
    'bar' => 'foo'
], time() + 3600);

Gets a cookie by name

use Josantonius\Cookie\Cookie;

$cookie = new Cookie();

$cookie->get('foo'); // null if the cookie does not exist

use Josantonius\Cookie\Facades\Cookie;

Cookie::get('foo'); // null if the cookie does not exist

Gets a cookie by name with default value if cookie does not exist

use Josantonius\Cookie\Cookie;

About cookie expires

• The expires parameter used in several methods of this library accepts the following types: int|string|DateTime.

  • Integers will be handled as unix time except zero.

  • Strings will be handled as date/time formats. See supported Date and Time Formats for more information.

    $cookie = new Cookie(
        expires: '2016-12-15 +1 day'
    );

    It would be similar to:

    $cookie = new Cookie(
        expires: new DateTime('2016-12-15 +1 day')
    );

  • DateTime objects will be used to obtain the unix time.

• If the expires parameter is used in the set or replace methods, it will be taken instead of the expires value set in the cookie options.

  $cookie = new Cookie(
      expires: 'now +1 minute'
  );
  
  $cookie->set('foo', 'bar');                        // Expires in 1 minute
  
  $cookie->set('bar', 'foo', 'now +8 days');         // Expires in 8 days
  
  $cookie->replace(['foo' => 'bar']);                // Expires in 1 minute
  
  $cookie->replace(['foo' => 'bar'], time() + 3600); // Expires in 1 hour

• If the expires parameter passed in the options is a date/time string, it is formatted when using the set or replace method and not when setting the options.

  $cookie = new Cookie(
      expires: 'now +1 minute', // It will not be formatted as unix time yet
  );
  
  $cookie->set('foo', 'bar');   // It is will formatted now and expires in 1 minute
