相对路径在 html 属性中不起作用。php 文件

Question

I tried to use a URL in the parent directory of the root but it's not working in the HTML attribute of the PHP file.

<?php 
    include ("../func.php"); // working, will include the file in the parent directory 
?>  
<img src='../testimg.png'/>  <!-- It only looks inside the current directory-->  
<img src='..../../testimg.png'/>   <!-- If I mess around with the relative path, it still looks inside the current directory-->

However, if I delete the PHP code and change the file extension to.html, the relative path in img src works normally.

Why is this happening and how could I solve the problem? I am wondering is there any PHP configuration file I need to adjust?

I have been stuck with this problem for a long time and googled a lot but didn't find a working solution. I would be appreciated for any help.

Answer 1

I tried your code in my local with the following directory structure

root_folder
    |---my_folder
        |__index.php -> (this file contained your code above)
    |---func.php
    |---testimg.png

<img src='../testimg.png'/> showed my image perfectly.
