can insert string into $_SESSION, but not INT

[niche]

this works: array(1) { ["snpos"]=> string(1) "5" }$pos = 5;$pos = strval($pos);$_SESSION['snpos'] = $pos;echo var_dump($_SESSION) . '</br>'; but this doesn't: array(1) { ["snpos"]=> int(5) } $pos = 5;$_SESSION['snpos'] = $pos;echo var_dump($_SESSION) . '</br>'; Why can't I define a session key with a INT value?

did you check the manual page?http://www.php.net/manual/en/session.examples.basic.phpit's right there at the top:

The keys in the $_SESSION associative array are subject to the same limitations as regular variable names in PHP, i.e. they cannot start with a number and must start with a letter or underscore.

except in this case 5 is the value of the key correct?

Hmm, I just read your question

Why can't I define a session key with a INT value?

and replied to that.So upon reflection, what about this:

array(1) { ["snpos"]=> int(5) }

is a problem?
