问题描述
我需要经历四个条件,我认为最好在 PHP 中使用 switch
语句.但是,我需要检查一个整数是否小于等于,或者大于等于.
I have four conditions that I need to go through and I thought it would be best to use the switch
statement in PHP. However, I need to check whether an integer is, let's say, less than or equal, or greater than and equal.
switch ($count) {
case 20:
$priority = 'low';
break;
case 40:
$priority = 'medium';
break;
case 60:
$priority = 'high';
break;
case 80:
$priority = 'severe';
break;
}
使用 if()
语句将如下所示:
With an if()
statement it would look like the following:
if ($count <= 20) {
$priority = 'low';
}
if ($count <= 40) {
$priority = 'medium';
}
这在 switch-case
中可行吗?
推荐答案
解决这个问题的更一般的情况是:
A more general case for solving this problem is:
switch (true) {
case $count <= 20:
$priority = 'low';
break;
case $count <= 40:
$priority = 'medium';
break;
case $count <= 60:
$priority = 'high';
break;
default:
$priority = 'severe';
break;
}
