Well, can't say I see the same problem:
<?php
$_SESSION['foo'] = array("hi"=>"bye");
print_r($_SESSION['foo']);
echo "\n\n";
print is_array($_SESSION['foo']);
Outputs:
X-Powered-By: PHP/4.2.2
Content-type: text/html
Array
(
[hi] => bye
)
1
Which is what I'd expect it to show.
Now how did you assign categories?
Maybe the var is a scalar and is actually "Array (\n [0] => '1';\n [1] =>
'12';" and you are confused.o
If you are saying:
$_SESSION['categories'] = "Array (
[0] = '1';
";
Then it IS a scalar. Try this:
print ":::{$_SESSION['categories']}:::";
If you get this:
:::Array:::
Then I have no clue what the problem is
If you don't get that, then we know what your problem is.
