PHP包括不工作？功能不包括在内 [英] Php include not working? function not being included

问题描述

这是情况的完整背景：

我最近买了一台新的Mac，我是一名php开发人员，因此我下载了MAMP并开始开发。

p>

首先我注意到我的包含没有被包含，但我通过配置我的 php.ini 来改变它。

例如我有一个名为 functions.php 的文件：

 <？php 
函数doit（）{
 echodid it; 
} 
？> 
  

以及包含它的文件，名为index.php

 <？php include（functions.php）;度特（）;？> 
  

我得到这个错误信息

致命错误：在第4行的index.php中调用未定义函数doit（）

因为他们有同样的问题让我解释什么和为什么出问题。

如果你包含一个不在你的目录中的函数（例如c：//或file： //），而是包含使用http。 include只能返回文件中回显的内容，但不会显示类似变量或函数的内容。所以总是通过一个目录

包含函数和变量

Here is the full context of the situation:

I recently got a new Mac, I'm a php developer so I downloaded MAMP and started developing.

First I noticed that my includes were not being included, but I changed that by configuring my php.ini.

However now, when I try to include a file with a function it does not recognize the function.

For example I have a file named functions.php:

<?php
function doit(){
    echo "did it";
}
?>

and a file that includes it called index.php

<?php include("functions.php"); doit();?>

and I get this error message

Fatal error: Call to undefined function doit() in index.php on line 4

解决方案

So if anyone ever stumbles on this forum because they are having the same issue let me explain what and why it went wrong.

If you include a function not in your directory(e.g c:// or file://) but instead include using http. The include can only return what was echoed in the file, but something like a variable or function will not be shown. So always include functions and variables through a directory
