问题描述
我有一个开关,在极少数情况下我可能需要跳到另一个案例,我正在寻找这样的东西:
I have a switch where in very rare occasions I might need to jump to another case, I am looking for something like these:
switch($var){
case: 'a'
if($otherVar != 0){ // Any conditional, it is irrelevant
//Go to case y;
}else{
//case a
}
break;
case 'b':
//case b code
break;
case 'c':
if($otherVar2 != 0){ // Any conditional, it is irrelevant
//Go to case y;
}else{
//case c
}
break;
.
.
.
case 'x':
//case x code
break;
case 'y':
//case y code
break;
default:
// more code
break;
}
是否有任何 GOTO 选项,我在某处发红但找不到它,或者可能是其他解决方案?谢谢.
Is there any GOTO option, I red somewhere about it but can't find it, or maybe another solution? Thanks.
推荐答案
您需要 PHP 5.3 或更高版本,但这里:
You need PHP 5.3 or higher, but here:
这里是 http://php.net/的 goto 功能手册/en/control-structures.goto.php
Here is the goto functionality from http://php.net/manual/en/control-structures.goto.php
<?php
$var = 'x';
$otherVar = 1;
switch($var){
case 'x':
if($otherVar != 0){ // Any conditional, it is irrelevant
goto y;
}else{
//case X
}
break;
case 'y':
y:
echo 'reached Y';
break;
default:
// more code
break;
}
?>
