包括调用文件中无法访问的文件变量

Question

Note: The variable is set in included file, the issue is not an undefined variable, hence the duplicate question is not relevant to my question. PHP: "Notice: Undefined variable", "Notice: Undefined index", and "Notice: Undefined offset"

Edit: i just noted my localhost include path is set to C:\xampp\php\PEAR when i did echo get_include_path(); but i don't get error for included file not found rather the variable is undefined.

I have 2 files in C:/xampp/htdocs/test/ index.php config.php

Content of index.php:

require 'config.php';
echo $name;

Content of config.php:

$name = 'xyz';

And i get Notice: Undefined variable: name Where the $name = 'xyz' is in config.php which is included before using the variable.

I have to yet test it on live server. Please guide.

Holly Cow.

There was no error in the file. The php start tag was not correct, it was short tag <? ?> instead of <?php ?> this was causing the issue.

i'm using php7 on my localhost. but of course t would work on older version of PHP and hosting.
