if和else在我的PHP代码中都是真的

Question

i wonder that both if and it's else are true.

i got $apple_id_num from the input select form and it is a number but in string type like "7" and it is how many ids that user wants.so i convert it to integer

now i want to check if it is not more that what i have available in my database. but statements under conditions ($num_rows<$id_num) and if ($num_rows>=$id_num) both are running.

what i'm doin wrong?

here is my code:

function getAppleID($apple_id_num)
{
    $sqli=new mysqlii();
    $apple_ids=$sqli->SelectFromDB($apple_id_num);
    $num_rows=$sqli->num_rows;
    $id_num=(int)$apple_id_num;

    if ($num_rows>=$id_num){
        $this->printAppleID($apple_ids,$num_rows);
        //$sqli->updateRows();
        echo"else if running";
        return $apple_id_num;
   } else if ($num_rows<$id_num)
          echo "if statement was rungning";    
}

Try this code. always write intended code. Sometimes you may miss a } :P Use elseif in place of else if.

function getAppleID($apple_id_num)
{
    $sqli=new mysqlii();
    $apple_ids=$sqli->SelectFromDB($apple_id_num);
    $num_rows=$sqli->num_rows;
    $id_num=(int)$apple_id_num;
    if ($num_rows>=$id_num) {
       $this->printAppleID($apple_ids,$num_rows);
       //$sqli->updateRows();
       echo"else if running";
       return $apple_id_num;
    } elseif ($num_rows<$id_num) {
       echo "if statement was rungning";
    }    
}
