Remove quote from an array in json (Php)

I tryed to remove the quote from my json output, but nothing work...

1 => array(

           'y' => str_replace('"','',$behaviour[5]['wcount']),
           'name' => 'Slice Name B'
        ),

Output

{"y":"3","name":"Slice Name B"}

I need to remove the string "3"

I tryed str_replace('"','',$behaviour[5]['wcount']) and str_replace("'","",$beha开发者_JAVA技巧viour[5]['wcount']);

Someone can help me please ?

Try this instead:

1 => array(
           'y' => intval($behaviour[5]['wcount']),
           'name' => 'Slice Name B'
        ),

If you're running PHP 5.3.3. or better, you can pass JSON_NUMERIC_CHECK to json_encode which should do what you want:

$encoded = json_encode($data, JSON_NUMERIC_CHECK);
