我如何使开关案件检查所有案件

Question

switch (true){
   case X==Y:
    //do something 
   case X==Z:
    //do something 
   case X has 0 :
    //do something 
}

Answer 1

如果您想改变If...else的风格，并想使用switch...case

所以你可以这样试试

$test = true;
$x=1;$y=1;$z=2;//uncomment any one and check
//$x=1;$y=2;$z=1;//uncomment any one and check
//$x=0;$y=1;$z=1;//uncomment any one and check
switch ($test){
   case $x==$y:
        echo "x==y";
        break;
   case $x==$z:
        echo "x==z";
        break;
   case $x==0 :
        echo "x has 0";
        break;
   default:
        echo "he!he!he!he!he!he!";
}

取消注释任意一个并检查所有条件
