if var was abc1234 then it would return NULL, is that correct?

False if the value is not valid, null if the value does not exist (for example with input_get or input_get_args). In the case of filter_data, as you pass the variable, it will be either false or the correct value. here it returns '0'

Please show me some code, "here" is not really helpful. For example: $ php -r '$var=1234; var_dump(filter_data($var, FILTER_VALIDATE_INT));' int(1234) $ php -r '$var=ab1234; var_dump(filter_data($var, FILTER_VALIDATE_INT));' bool(false) --Pierre
