我是PHP的新手,我会尝试输入会显示其等效的学生的成绩。
这相当于成绩:
1.00 (96-100);
1.25 (93-95);
1.50 (90-92);
1.75 (87-89);
2.00 (84-86);
2.25 (81-83);
2.50 (78-80);
2.75 (76-77);
3.00 (75);
5.00 (Below 75);
这是我的代码:
<form method="POST">
<td>
<input type="text" id="someid" name="number"
maxlength="3" Onkeypress="return isNumberKey(event)" required />
<?php
$number='';
if (!empty($number)) {
switch (true) {
case $number>=96&& $number<=100:
break;
case $number>=93&& $number<=95:
break;
case $number>=90&& $number<=92:
break;
case $number>=87&& $number<=89:
break;
case $number>=84&& $number<=86:
break;
case $number>=81&& $number<=83:
break;
case $number>=78&& $number<=80:
break;
case $number>=76&& $number<=77:
break;
case $number>=75:
break;
}
?>
我的问题是我如何输入示例90的等级,使用PHP显示相当于90?
