从子函数中打破父函数（PHP优先） [英] Breaking a parent function from within a child function (PHP Preferrably)

问题描述

我遇到了如何在不修改父代码的情况下破解或终止父函数的执行，使用PHP

I was challenged how to break or end execution of a parent function without modifying the code of the parent, using PHP

我找不到任何解决方案，除了死（）;在孩子中，这将终止所有的执行，所以在父函数调用之后的任何事情都会结束。任何想法？

I cannot figure out any solution, other than die(); in the child, which would end all execution, and so anything after the parent function call would end. Any ideas?

代码示例：

code example:

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";

推荐答案

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";
