You can use sessions to store complex data types such as
objects and arrays simply by treating them as standard variables, as this code
shows:
$myarr["0"] = "Sunday";
$myarr["1"] = "Monday";
$myarr["2"] = "Tuesday";
$myarr["3"] = "Wednesday";
$myarr["4"] = "Thursday";
$myarr["5"] = "Friday";
$myarr["6"] = "Saturday";
$_SESSION["myarr"] = $myarr;
You can also use the serialize( ) and unserialize( )
functions to explicitly convert to and from a string. If you do not call
serialize( ) yourself, PHP will do it for you when the session data is
written to diskmany do rely on this, but I would say it's best to be explicit
and serialize( ) data yourself.
If you are trying to store objects in your session and you find
it is not restoring the class name properly, it is probably because you started
the session before you had the class defined. This problem is often encountered
by people who use the session.auto_start directive in
php.ini.
