在PHP中使用GOTO命令? [英] GOTO command in PHP?

问题描述

我听说有传言说PHP正在计划引入"goto"命令.它应该在做什么?

I've heard rumors that PHP is planning on introducing a "goto" command. What is it supposed to be doing?

我尝试了一下搜索，但是没有发现任何描述性很强的东西.我知道这不会是类似"GOTO 10"的命令...

I've tried searching a bit, but haven't found anything awfully descriptive. I understand that it won't be a "GOTO 10"-like command...

推荐答案

他们不是在添加真实的GOTO，而是将BREAK关键字扩展为使用静态标签.基本上，它将增强突破嵌套if语句的 switch 的能力.这是我发现的概念示例:

They are not adding a real GOTO, but extending the BREAK keyword to use static labels. Basically, it will be enhancing the ability to break out of switch nested if statements. Here's the concept example I found:

<?php
for ($i = 0; $i < 9; $i++) {
    if (true) {
        break blah;
    }
    echo "not shown";
    blah:
    echo "iteration $i\n";
}
?>

当然，一旦GOTO的谣言"出炉了，就没有什么可以阻止一些邪恶的人传播另外的 COMEFROM 笑话了.保持警惕.

Of course, once the GOTO "rumor" was out, there was nothing to stop some evil guys to propagate an additional COMEFROM joke. Be on your toes.
