$data= "a:5: {i:0;s:6:"entire";i:1;s:6:"hourly";i:2;s:5:"daily";i:3;s:6:"weekly";i:4; s:7:"monthly";}";
$dat = unserialize($data);
if (is_array($dat))
{

I believe count($dat) should return the quantity of array to me... and the turn is 1.

Hi,

count($dat) will return the exact count in the array.

And please try this:

var_dump($dat);

And also please set the php.ini for getting warnings and notices.

error_reporting  =  E_ALL


Hope this will help you.

Regards.

Hi,

var_dump  Dumps information about a variable.

This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.

Look at the php folder in your machine for php.ini (Look at the php installation folder. May be c:/windows or c:\xampp/php  if you are using xampp).


And what output you get with var_dump() ?

Hope this will help you.

Hi,

Look at the php folder in your machine for php.ini (Look at the php installation folder->c:\xampp\php\php.ini  if you are using xampp).

And do :

set the php.ini for getting warnings and notices.

error_reporting  =  E_ALL


And try again. You will get atleast one notice.

Hope this will give you the error.

And please give me the feedback.

Regards
