php - 致命错误：调用未定义函数 smug_1()

Question

很抱歉打扰所有忙碌的人，我只是无法弄清楚为什么该功能不起作用。反复试验花了 50 分钟。给出的错误是针对第 15 行“case 'smug': smug_1(); break;”

<?php
include "globals.php";

if ($ir['jailtime'] > 0) {
    print "<center>The docks are closed to jail birds come back when thay release you</center>";
    exit;
}
if ($ir['hospital'] > 0) {
    print "<center>You cant go sailing while in hospital</center>";
    exit;
}
switch ($_GET['action']) {
case 'smug':
    smug_1();
    break;
case 'smugsub':
    smug_1_sub();
    break;
case 'smug2':
    smug_2();
    break;
case 'smugsub':
    smug_2_sub();
    break;
case 'smug3':
    smug_3();
    break;

感谢您花时间帮助我。:)

您的函数是在if() ...块内定义的，因此在匹配 if 块之前它们不可用于解析器。if()在你的块之外定义它们！

您必须在输出 .php 文档开始之前加载/包含所有功能（功能代码）...

所以

必须首先包含/加载函数（并由 PHP 读取）
然后你可以在一个文件中调用它们！

显然，您的“输出”代码是在函数代码之前设置的（因此 PHP 无法执行函数，因为它不知道此时存在函数）。因此，您必须以其他方式编写代码。

<?php

include "globals.php";

试试看。唯一的问题是 globals.php 可以在函数之前或之后（因为我不知道 globals.php 做了什么）.centersmugsub
