Storing a function inside a php session?

Question

PHP

Next code:

$_SESSION['test'] = function(){
  echo 'test';
};

Spitting error

Fatal error: Exception thrown without a stack frame in Unknown on line 0

And I desperately need to store functions inside the session, or somehow transfer them to another script.
What is the best way to implement this?

Answer 1

Solved thanks to @LastDragon

Out of the box - nothing, but you can see (did not use it myself) PHP Super Closure ("a library that allows you to serialize closures in PHP", found in one of the digests ).

Answer 2

If it's desperate, maybe eval () of the string will do?

Answer 3

Weird:

php > $func = function() { echo 'test'; };
php > $func();
test
php > session_start();
php > var_dump($_SESSION);
array(0) {
}
php > $_SESSION['test'] = $func;
php > $_SESSION['test']();
test

Do you have a standard session storage mechanism?
