I recently had the need to extract the value of a Set-Cookie response header in PHP. Google lead me
http_parse_cookie
. Unfortunately,
http_parse_cookie
requires
pecl_http
which isn’t available with PHP out of box, and is a pain to install.
Other Google results suggest
defining your own function
.
After a bit of research, I found the
SetCookie
class
in
Guzzle
. The implementation is really clean and is the best option for parsing Set-Cookie headers in PHP in my opinion.
Here’s a quick overview of how to use it…
How To Use It
Usage in pretty simple. The easiest way to use Guzzle is via
composer
. Once you’ve
autoloaded
the library, you pass the
Set-Cookie
header as an argument to
GuzzleHttp\Cookie\SetCookie
’s
fromString
method as follows…
use GuzzleHttp\Cookie\SetCookie as CookieParser;
$cookieParser = new CookieParser;
$cookie = $cookierParser->fromString('Set-Cookie: key=value');
Now you can conveniently interact with the $cookie…
echo $cookie->getName(); // key
echo $cookie->getValue(); // value
You can also access many other aspects of the cookie
echo $cookie->getExpires();
echo $cookie->getHttpOnly();
echo $cookie->getSecure();
Check the Set-Cookie class for a full list of available methods…
