var_dump not printing the integer values

Question

I am trying to read some values from the membase. I observer that when there is any integer the following command is not working.

 var_dump($memcache->get("keyset123"));
 print_r($memcache->get("keyset123"));

If the get result is a string the above command prints. If the get result is a Integer the above commands are printing none.

vardump prints =string(0) "" print_r prints none.

can you please tell me what is the issue

That is because the $memcache->get() call is returning a string value. Your problem lies elsewhere (likely deeper within the code in use), not within var_dump().

Look into what you're storing within whatever is inside of the variable $memcache.

I agree it could may not be issue with the var_dump(). – Kishore Thota Jun 04 '11 at 03:39
But I am not getting what I am missing in the membase, get function. can you please help me in that regard – Kishore Thota Jun 04 '11 at 03:39
$memcache->get() always returns string. will that be an issue not printing the value? – Kishore Thota Jun 04 '11 at 03:41

http://us3.php.net/manual/en/memcache.get.php yep, only returns strings...which means you need to know when you're supposed to be storing as strings, and typecast to integer or float appropriately. Again, verify what you're storing inside of the memcache and see what it is going in. – damianb Jun 04 '11 at 03:44
I tried different permutations that I know I stil see the issue – Kishore Thota Jun 04 '11 at 05:26

var_dump($memcache->get("keyset123"));
//outputs
//string(0) ""

Memcached is storing an empty string at the key "keyset123", otherwise you would be getting FALSE (key doesn't exist) or NULL (key exists, but no value exists)

James, keyset123 is having a integer value in the database. why am I not able to get that value? If I keep the value as string it works – Kishore Thota Jun 04 '11 at 03:46
