从子函数中破坏父函数(PHP Preferrably)

Question

我遇到了如何在不修改父代码的情况下使用PHP来中断或结束父函数的执行的挑战

除了die()之外,我无法找出任何解决方案; 在子节点中,它将结束所有执行,因此在父函数调用之后的任何内容都将结束.有任何想法吗？

代码示例:

function victim() {
    echo "I should be run";
    killer();
    echo "I should not";
}
function killer() {
    //code to break parent here
}
victim();
echo "This should still run";

Answer 1

function victim() {
    echo "I should be run";
    killer();
    echo "I should not";
}
function killer() {
    throw new Exception('Die!');
}

try {
    victim();
} catch (Exception $e) {
    // note that catch blocks shouldn't be empty :)
}
echo "This should still run";
