====== CookieHandler::WriteJsonContent() ======
----

===== Definition =====

Converts an array to a JSON string and sets it as cookie content. \\
e.g. An array like ''array ('a'=>1, 'b'=>2, 'c'=>3)'' is written als content string ''{"a":1,"b":2,"c":3}''. \\
Optional a cookie lifespan can be set when the cookie is written as it is done in [[libraries:cookiehandler:cookiehandlerclass:setvalidity|SetValidity()]].

**Important!** As a cookie is part of the HTTP header, the writing of a cookie has to be done before the first output is sent to the browser (even blanks etc.).

<code php>
void WriteJsonContent ( $JsonArray, [$Days = NULL, [$Hours = NULL, [$Minutes = NULL, [$Seconds = NULL]]]] )
