php三元运算
$a = 2;
$a == 1 ? $test="企业" : ($a==2 ? $test="地区" : $test="其他地方");

echo $test;


先判断$a是否为1 如果是 直接输出 企业,如果不是 继续判断 相当于else里面又嵌套一个if 如果等于2输出地区 如果不是输出 其他地方

等价于

$a = 2;

if($a == 1) {

echo $test="企业";

} else {
if($a == 2){

$test = "地区";

} else {

$test="其他地方";

}

}

echo $test;


或者

if($a == 1) {

echo $test="企业";

} else {
$a==2 ? $test="地区" : $test="其他地方";

}
