Question

你的代码风格太诡异了吧?
$tireqty=100;
if($tireqty<10)
$discount=0;
elseif($tireqty >=10 && $tireqyt<=49)
$discount=5;
elseif($tireqty >=50 && $tireqyt<=99)
$discount=10;
else if($tireqty >=100)
$discount=15;
echo $discount; 应该是15吧,如果是5,那...见鬼了!

Answer 1

elseif($tireqty >=10 && $tireqyt<=49)
/*                         ***    */
 elseif($tireqty >=50 && $tireqyt<=99)
/*                         ***    */拼写错误

Answer 2

$tireqty=100;
{if($tireqty<10)
$discount=0;
elseif($tireqty >=10 && $tireqyt<=49)  //该行$tireqyt拼写错误!
$discount=5;
        elseif($tireqty >=50 && $tireqyt<=99)      //该行$tireqyt拼写错误!
$discount=10;
        else if($tireqty >=100)
$discount=15;}
echo$discount;
