Question

as shown above may i know is there a way to check a return query is null? which means it contains zero value.

I have the following sql query statements:

$result_number_country_malware = $db->query("SELECT sum(download_hits) as total_hits from date1_dcerpc; ");

so how do i check whether $result_number_country_malware is null? This is a PDO object, hence i can’t use normal operators to check.

thanks for any help in advance!

Answer 1

did you try $result_number_country_malware->count() ?

it would be similar to mysql_num_rows($result); if its 0 it is null, that being said..

if($result_number_country_malware->count()){
NOT NULL
}
else
{
NULL
}

I am not a PDO expert by any means, but i use doctrine and this seems very similar.
