Multiple values in one cookie

Expand Post »

Hi All

I am a bit of a begginer in PHP.
How do I store multiple vales in a cookie?
I am going along the lines of:

php Syntax (Toggle Plain Text)
$data = array('apple'=>'green',		'orange'=>'orange',
	'banana'=>'yellow');
$data = array('apple'=>'green',		'orange'=>'orange',
	'banana'=>'yellow');

then something like (not sure about the sytax here)::

php Syntax (Toggle Plain Text)
$var=implode($data);
setcookie('data', $var, time() +3600);
$var=implode($data);
setcookie('data', $var, time() +3600);

Basically how do I get the information into and out of the cookie.

Thanks in advance for any help.

Re: Multiple values in one cookie

Hi,

Why don't you concatenate values in a string like

PHP Syntax (Toggle Plain Text)

   apple,orange,mango
 and then store it in cookie.

Re: Multiple values in one cookie

I really need it to be an associative array that is stored in the cookie and then be able to output the relevant data. If that makes any sense.

Re: Multiple values in one cookie

Well if you want to implode the values and store it in the cookie then you'd explode it to retrieve it as an array.

php Syntax (Toggle Plain Text)
$array = array('orange', 'green', 'blue');
$string = implode(',', $array); // 'orange,green,blue'
$second_array = explode(',', $string); // array('orange', 'green', 'blue');
$array = array('orange', 'green', 'blue');
$string = implode(',', $array); // 'orange,green,blue'
$second_array = explode(',', $string); // array('orange', 'green', 'blue');

Re: Multiple values in one cookie

Thanks for all the help.
I know how to do the array part but I cannot get it into my head how to put the array into a single cookie and then get the data back out of the cookie.
I have spent most of yesterday googling for a solution with no real luck.

Thanks again in advance.

Re: Multiple values in one cookie

Well you did it in your example. All I did was explain the correct syntax for implode/explode. Also, see www.php.net/cookies

Re: Multiple values in one cookie

Hi
Thanks again for all the help, my head is going round and round as I have been at thsi for so long now. i right in saying to set the cookie I :

php Syntax (Toggle Plain Text)
$data = array('apple'=>'green', 'orange'=>'orange',
'banana'=>'yellow');
$var=implode( ',', $data);
setcookie('data', $var, time() +3600);
$data = array('apple'=>'green', 'orange'=>'orange',
'banana'=>'yellow');
$var=implode( ',', $data);
setcookie('data', $var, time() +3600);

and that has set the cookie?
I know how to set and then get everything out of a normal cookie
I alsoknw how to use the array but put them both together and I have a total block. I just cannot get my head round getting the data from within the array that is stored in the cookie. I have read your link but it is not helping me as I think my brain is fried.

Any help very very gratefully accepted.

Re: Multiple values in one cookie

If you know how to set and get data from the cookie I just gave you how to use implode/explode, just put them together. You already did the first part in your original post.
