validate int which exceeds PHP_INT_MAX value (2147483647) in zend framework

[rattlingabhi]

Any workaround to validate an int field which exceeds PHP_INT_MAX (2147483647 on 32 bit) value? The code I am using in Zend framework is:\[code\]'int_input' => array( 'allowEmpty' => true, 'Zend_Validate_Int', array('Zend_Validate_Between',0,4000000000), 'message' => 'Int must be between 1 and 4,000,000,000.' )\[/code\]Thanks.
