serialize problem...

[ingchun]

Dear all:

let say $choice is an array with 5 elements that i passed to the following script....

<?php
$choice_s=serialize($choice);
setcookie("choice_cookie",$choice_s);
?>

above is ok for me. array has been serialized and cookie has been set. but when i try to get the array back by following script in any page i designed, it failed. really wonder why?

<?php

$choice_cookie=$HTTP_COOKIE_VARS["choice_cookie"];
$choice=unserialize($choice_cookie);

$count=count($choice);
echo $count; //give me output 1 only....how come????

?>

hope you all can help me. thanks

Because that's what the count function does. It tells you how many items there are in an array.

Do you want the first ITEM from the array?

If so, then you want $choice[1]

If you want all the values of the array, then you have to concatenate the array into a string like so:

$choicesum = "";
foreach ($choice as $temp) {
$choicesum .= $temp;
}
echo $choicesum;

ingchun,

Try outputting $cookie_s in one script and $choice_cookie in the other one, and see if they are the same. My guess is that they are not, because of the HTTP transmission. Try setting the cookie using urlencode, e.g.

$choice_s=serialize($choice);
setcookie("choice_cookie",urlencode($choice_s));

And in your other script you'd have to call urldecode() before you unserialize.

feldon23,

ingchun said that there are 5 elements in the array, so a count of 1 is wrong 🙂
