布尔值切换/反转

PHP中是否有切换/反转boolean值的功能?

Is there a function for switching/inverting boolean value in PHP?

喜欢...的快捷方式:

Like... a shortcut for:

if($boolean === true){
    $boolean = false;
}else{
    $boolean = true;
}

推荐答案

是的:

$boolean = !$boolean;

如果不是布尔值，可以使用三元构造:

if it's not a boolean value, you can use the ternary construction:

$int = ($some_condition ? 1 : 2); // if $some_condition is true, set 1
                                  // otherwise set 2
