我想在 php 和 codeigniter 库中使用switch
和case
,我尝试如下代码,但我没有收到输出。我该怎么办?
演示: http ://codepad.viper-7.com/Wq0Noj
function indicators() {
$CI = &get_instance();
$Year = '1355';
$Month = '03';
switch ($Year) {
case 1354:
$key=array('0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6','0.6');
$output = $key[$Month-1];
break;
case 1355:
$key=array('0.6','0.7','0.2','0.4','0.7','0.1','0.7','0.2','0.5','0.9','0.4','0.8');
$output = $key[$Month-1];
break;
echo $output; // The output should be: 0.7
}
}
