PHP library to save utm parameters from url into cookie for later use. PHP 7.1 is required for version 2.0.0+. If you need PHP 5.4+ compatibility use 1.0.6 version.

UtmCookie saves utm parameters from url into cookie with defined lifetime (default 7 days). Than cookie (utm) can be used later without parsing google or any other cookies.

It handles utm parameters:

• utm_campaign
• utm_medium
• utm_source
• utm_term
• utm_content

You can get them with original name or wihout "utm_" (for example just "source" for "utm_source" - you can use both) - see examples.

Since version 2.0.2 you can rewrite these cookies just with call UtmCookie::save($array) where $array should contains keys allowed by UtmCookie::$allowedUtmCookieKeys (default are allowed utm parameters names).

Get composer and add this in your requires section of the composer.json:

{
    "require": {
        "xsuchy09/utm-cookie": "*"
    }
}

and then

composer install

UtmCookie::init(); // just init - read utm params and cookie and save new values (is auto called by first call of UtmCookie::get method)
UtmCookie::get(); // get all utm cookies as array
UtmCookie::getObject(); // get all utm cookies as object (stdClass)
UtmCookie::get('utm_source'); // get utm_source
UtmCookie::get('source'); // get utm_source

$dateInterval = DateInterval::createFromDateString('7 days');
UtmCookie::setLifetime($dateInterval);

UtmCookie::setName('utm');

Default TRUE. If set to false, utm value is overwite only if set (others will stay).

UtmCookie::setOverwrite(false);
